Willis (wrist) only managed three tackles (two solo) in Sunday's win over Philadelphia.

Willis turned in his worst performance of the season Sunday, failing to make a statistical impact on the game.

Willis (wrist) was a full participant in Wednesday's practice, the Sacramento Bee reports.

In addition to imparting the minor nature of his wrist injury, which required the use of wrist guards during practice, Willis said, "I'll be fine."

Prior to drills commencing, Willis was seen wearing a brace on his wrist, according to Matt Maiocco of CSN Bay Area.

Willis is as consistent as they come at the linebacker position. He is on pace for another 100+ tackle season.

Willis recorded eight tackles (seven solo) in Sunday's 28-20 loss to the Bears.

Willis recorded six tackles and picked off a pass in Sunday's win over Dallas.

Willis didn't rack up the tackles like he usually does, but the interception was a nice surprise for his IDP owners. He should be a great source of tackles going forward with NaVorro Bowman (knee) sidelined for the majority of the season.

Willis (undisclosed) wasn't listed on the 49ers' injury report Wednesday, CSN Bay Area reports.

Willis missed the entirety of the preseason with an ailment that the organization never revealed, but Wednesday's report was without his name, making him available for Week 1 in Dallas. The IDP force should be utilized in most leagues for his all-around production.

There is no injury to report here, coach Jim Harbaugh simply decided to give his stud linebacker the day off. He is completely over the thumb injury he sustained at the end of the 2013 season.

Patrick Willis (thumb surgery) has been a full participant in 49ers OTAs.

Willis went under the knife shortly after the 49ers' NFC Championship Game loss. Willis was named to his seventh consecutive Pro Bowl in 2013, but was left off the All-Pro squad. Willis turned 29 in January.

Patrick Willis recently underwent surgery on his left thumb and is in a cast.

What was exactly wrong with Willis' thumb is unknown; he wasn't on the injury report ahead of the NFC Championship game. It's possible he suffered the injury in Seattle. Either way, Willis should be ready for minicamp in June.
