Defensive tackle Anthony McFarland, an important contributor in the Colts' run to a Super Bowl title last season, might miss extensive playing time after injuring his knee in training camp.
The 29-year-old, obtained from the Bucs in a midseason trade last year, hurt the patella tendon Friday and missed Saturday's controlled scrimmage. An MRI exam showed the extent of the injury, the team said.
Colts coach Tony Dungy called the injury serious and that it might need surgery but did not give details on how it happened.
"It's a long-term injury," said Dungy, who also coached McFarland with Tampa Bay. "It's (surgery) something that we're contemplating. It's something that I think is going to happen."
After coming from the Bucs, where he played seven-plus seasons, McFarland helped shore up the Colts' run defense in the playoffs.

His signing leaves Oakland's JaMarcus Russell (No. 1 overall), the Jets' Darrelle Revis (14th) and Cleveland's Brady Quinn (22nd) as the only unsigned draft picks.
