Three Indians prospects -- infielder Beau Mills, outfielder Jerad Head and right-hander Josh Tomlin -- were charged with felonious assault after a fight at an Ohio nightclub earlier this month.

The alleged attack left 25-year-old Theodore Zeman III with a punctured lung and rib fractures. Mills, 23, and Head, 27, pleaded not guilty in Akron Municipal Court on Thursday. Mills is the son of Astros' manager Brad Mills. The 2007 first-round pick was ranked as the organization's No. 24 prospect by Baseball America over the winter.
