Marshall (shoulder) will need multiple throwing sessions before he can begin a rehab assignment, Mark Sheldon of MLB.com reports.

Marshall hasn't pitched since June 10, 2014. Reds manager Bryan Price was bullish on Marshall's chances at beginning a rehab assignment this season saying, " I don't think he's there yet. I don't think he's to the point where batting practice is to the immediate future. But I do believe because of his situation that if we get to the point where he can go out and face hitters, we'll do that. At this point in time, I don't think he's knocking on the door for that."

Marshall (shoulder surgery) has begun throwing bullpen sessions, but doesn't have a timetable to start facing hitters.

Marshall, who is out for the season, has been throwing every third day so far.

Marshall (shoulder) is expected to begin throwing again in six weeks, C. Trent Rosecrans of the Cincinnati Enquirer reports.

Marshall underwent a shoulder procedure in mid-May that is expected to keep him on the shelf for the remainder of the 2015 season. The soon-to-be free agent will likely have to showcase for teams to prove he's healthy before getting much attention on the market. At 32 years old and with several noteworthy procedures under his belt, he'll likely have to catch on with a low-risk, team-friendly deal.

Marshall will undergo surgery Wednesday to repair the torn anterior capsule in his left shoulder.

Shoulder issues have plagued Marshall over the past two years, and he's now slated for a second procedure on his left shoulder. His first, which was performed last June, was to remove unhealthy tissue from the area, and this one to repair the tear will keep Marshall out for the entire 2015 season. The 32-year-old will be a free agent this winter.

Marshall (shoulder) hasn't made good progress on his rehab.

This unfortunately is the norm, not the exception when it comes to shoulder injuries with pitchers. Marshall is on the 60-day DL and wasn't expected back soon anyhow, but this report suggests that it will be longer than 60 days.

Marshall (shoulder) was placed on the 60-day disabled list Sunday.

Marshall remains months away from a return, as he's yet to progress to a mound. With his placement on the disabled list, he will be unavailable until June, but he'll likely retake a spot in the bullpen upon his return.

Marshall (shoulder) isn't yet close to throwing from a mound.

Marshall is dealing with flexibility issues. "He can throw the ball OK," Reds manager Bryan Price said. "He still has a little bit of biceps tendinitis, which isn't of great concern. His evaluation went very well. The feeling is he needs more range of motion. That's consistent with someone who did a lot of work on the shoulder in the offseason. It's strong, but you've got to create the flexibility portion. That's given him some tedious achiness that we'd like to get out of there."

Marshall (shoulder) has resumed throwing from flat ground after being shut down at the beginning of spring training.

There's no timetable yet for when Marshall will throw from a mound, let alone when he'll be ready for game action. "It's a hard one to answer," Reds manager Bryan Price said. "What we're trying to do is get him to where he is completely pain free. He's been a little bit achy but nothing that would prevent him from throwing. It's a part of the process."

Marshall has inflammation in his pitching shoulder and has been shut down in his throwing program. "I was probably a couple of weeks from finishing my throwing program before I got out here," Marshall said. "I repeated my long-toss part every day and I started getting some cuff inflammation. I got here and noticed it, and they slowed me down a little bit until I was 100 percent healthy before advancing to flat ground and mound work. They kind of shut me down. I'm doing more stability stuff and my shoulder feels great the last couple of days. I am just waiting for the green light to resume my long-toss program."

Marshall is questionable at best for Opening Day. The Reds are just hoping that they get some healthy portion of the season. Opening Day is a goal, but isn't a finishing point.

Marshall (shoulder) might not be ready to return by Opening Day. "We've slowed down his throwing to make sure everything is OK," manager Bryan Price said. "We hope that's to pick up here in the next couple of days."

Marshall has been able to appear in only 31 games the last two seasons. Given the nature of the injury, anything that the Reds can get out of him has to be considered a bonus.

Marshall recently told MLB.com that he is progressing in his recovery from shoulder surgery. "My therapy is going great," Marshall said Sept. 23. "It really is. My strength is there. I still have a little range of motion work that I've been doing, but every day is better. I definitely feel like I have a new shoulder, so it's good and strong."

Shoulder issues have plagued Marshall's tenure with the Reds, limiting him to just 31 appearances over the past two seasons. He underwent surgery June 24 to repair a torn labrum and appears on track to begin a throwing program in early-to-mid November, with the hope being that he'll be 100 percent for spring training. His return would be a big boost to a bullpen that relied heavily on just two lefties in 2014, Manny Parra and Aroldis Chapman.

Marshall (shoulder) is rehabbing his surgically repaired shoulder 1 1/2 to 2 hours daily. "I can lift it up," Marshall said. "Most of the pain is gone. I think I'm ahead of schedule."

Part of Marshall's surgery included an infusion of stem cells designed to accelerate the healing process. Marshall is hoping that his progress mirrors that of the Brewers' Tom Gorzelanny, who had a similar procedure.

Sean Marshall underwent season-ending left shoulder surgery Tuesday.

The shoulder was debrided, with stem cells being infused to help the healing process. "They had a very, very optimistic feeling that the surgery went well," Reds manager Bryan Price said. "They're optimistic about a full recovery." Marshall is under contract for $6.5 million next season.

Sean Marshall will undergo surgery Tuesday to debride his left shoulder.

The Reds haven't revealed how long Marshall will be sidelined after the procedure, but it will surely be a season-ending operation. Marshall held a 7.71 ERA before landing on the DL last week and has been limited to just 31 appearances over the last two seasons due to shoulder issues. He's slated to earn $6.5 million from the Reds next season.

Reds placed LHP Sean Marshall on the 15-day disabled list with a left shoulder strain.

The 31-year-old southpaw has struggled since returning from the disabled list and continues to battle shoulder issues. In 15 games with the Reds, he posted a 7.71 ERA, 2.50 WHIP and 14/12 K/BB ratio over 14 innings.

Reds activated LHP Sean Marshall from the 15-day disabled list.

The 31-year-old southpaw was deemed good to go after appearing in two games on a minor league rehab assignment with Triple-A Louisville. He'll work in a setup capacity in front of interim closer Jonathan Broxton.

Sean Marshall (shoulder) could be activated from the disabled list as soon as next weekend.

Assuming he comes out of an appearance in an extended spring training game Saturday OK, Marshall will begin a rehab assignment with Triple-A Louisville on Tuesday. He'll make back-to-back appearances with the Bats before being activated next weekend if all goes well.

Reds placed LHP Sean Marshall on the 15-day disabled list, retroactive to March 21, with left shoulder inflammation.

Marshall battled more shoulder issues this spring after dealing with them for much of last season. However, he's been throwing off a mound and should be ready to rejoin the bullpen in a few weeks.

Sean Marshall (shoulder) faced hitters Wednesday for the first time this spring.

Marshall threw live batting practice, and Reds manager Bryan Price said the session went well. The southpaw was bothered by shoulder soreness earlier in spring but he appears past that at this point. He's still be a few weeks behind his teammates in terms of readiness for the season -- he'll almost certainly begin the season on the disabled list -- but Marshall should be back with the club before too long.

Sean Marshall (shoulder) will throw live batting practice Wednesday.

It will be the first time this spring that he's faced hitters. Coming back from shoulder tendinitis, Marshall will hang back in extended spring training but could join the Reds' bullpen sometime in April.
