The Super Bowl champions could be a missing a big contributor on defense for much of the season.
Indianapolis Colts defensive tackle Anthony McFarland injured his knee Friday and missed Saturday's controlled scrimmage.
Colts coach Tony Dungy called the injury serious and said McFarland might need surgery but didn't give details on how the injury happened or which knee was hurt.
"It's a long-term injury," Dungy said. "[Surgery is] something that we're contemplating. It's something that I think is going to happen."
The 300-pound McFarland, who was obtained in a trade from Tampa Bay last season and helped shore up the Colts' run defense in the playoffs, left the field early during Friday's workout. He was sent to Indianapolis for an MRI and has an injured patellar tendon.
"He's not going to be back in the next three or four weeks or anything like that," Dungy said.
