The Indianapolis Colts placed guard Donald Thomas on injured reserve Thursday, marking the second straight year his season has ended early, Colts head coach Chuck Pagano announced Thursday.
Thomas will need surgery after tearing his right quad muscle in practice on Wednesday. He missed 14 games last season with the same injury.
Thomas, 28, is in his second season with the Colts and was projected to be the starter at left guard after signing a four-year, $14 million deal with Indianapolis last offseason.
Thomas has also played for the New England Patriots, Detroit Lions and Miami Dolphins, the latter of which drafted him in the sixth round of the 2008 NFL draft.
