Philadelphia Eagles wide receiver Jeremy Maclin tore the ACL in his right knee and could miss the 2013 season.

"Maclin suffered a right knee injury during Saturday's practice which resulted in the fifth-year player being carted off the field," the Eagles said in a statement posted on their Web site.

The 25-year-old Maclin was hurt during non-contact drills without pads.

Maclin stayed on the ground for several minutes while trainers checked his right leg.

"He just came off the line of scrimmage and his knee buckled a little bit," wide receiver DeSean Jackson said. "It's an unfortunate situation."

Maclin, the Eagles' first-round pick in 2009 (No. 19 overall) is in the final year of his five-year rookie contract.

The wide receiver, who has dealt with several injuries and a lymphoma scare in 2011, has been productive.

"Maclin garnered a team-high 258 receptions over the last four seasons. In fact, no wide receiver in franchise history has caught more passes than Maclin in his first four years," the team said.

Maclin had 69 catches for 857 yards, with 7 TDs, last season. EFE
