PHILADELPHIA – Eagles wide receiver Jeremy Maclin tore the ACL in his right knee during practice Saturday and could miss the season.

Maclin went down at the end of a non-contact drill and appeared to be in pain while he was on the ground for several minutes. He was helped onto the cart and needed assistance getting off it and going into the team’s practice facility.

Maclin led the team with 69 catches for 857 yards and seven touchdowns last season, and the former first-round pick is in the final year of his rookie contract.

RAVENS: Tight end Dennis Pitta dislocated his hip in practice and is expected to be sidelined throughout the preseason and for the Sept. 5 regular season opener against Denver.

The injury occurred when Pitta collided with safety James Ihedigbo in the end zone vying for a pass from Joe Flacco. Pitta lay prone for several minutes before being carted off the field.

Pitta was preparing for his fourth season with Baltimore. The 6-foot-4, 245-pounder caught 61 passes for 669 yards and seven touchdowns last season.

BILLS: Buffalo is preparing to open training camp Sunday without Jairus Byrd, and with no indication of when the two-time Pro Bowl safety plans to report.

General Manager Doug Whaley said “hopefully soon,” but acknowledged that Byrd and his agent, Eugene Parker, have not informed the Bills of their intentions.

Contract talks are at a stalemate. The Bills retained Byrd’s rights in March, when they designated him their franchise player by offering a one-year, $6.9 million contract. Byrd has not accepted the offer, and is not required to attend training camp because he is unsigned.

GIANTS: Driving a car for more than 30 minutes, standing up straight for extended periods and getting into his football stance all had the same effect on defensive end Jason Pierre-Paul last season: It hurt, and it hurt a lot.

The 2011 All Pro player disclosed Saturday that he played last season in pain, and it didn’t go away until he had disc surgery on his back in June.

While he feels better now, the defensive catalyst is not sure whether he will be ready for the season opener at Dallas on Sept. 8, although that is his goal.

The Giants placed Pierre-Paul on the physically unable to perform list when the team reported to camp Friday, leaving him to continue his rehabilitation.

TEXANS: Running back Arian Foster is still recovering from a right calf strain, but said he feels good and shouldn’t be out of camp much longer.

The Texans placed him on the physically unable to perform list Thursday. The team said he’ll be out for a few days before working him back into a routine.

SEAHAWKS: Wide receiver Percy Harvin will get a second opinion on his sore hip next week in New York, and Coach Pete Carroll said all options remain for handling the injury.

Carroll said the range for treatment is still unknown. He said Harvin could be back on the field in a couple of weeks, or surgery may be the solution to solve the discomfort in the area around Harvin’s hip socket.

COLTS: Indianapolis put Pat Angerer and defensive end Fili Moala on the physically unable to perform list Saturday.

Angerer is recovering from offseason surgery on his right foot and Moala is trying to come back from surgery on his right knee.
