Mike Patterson returned to Eagles camp on Saturday, 10 days after collapsing and suffering a seizure during practice in Bethlehem, Pa.
Patterson, 27, didn't practice, but was in uniform doing strength and conditioning drills with trainer Rick Burkholder and several other teammates.
"I feel great," Patterson said.
The 300-pound defensive tackle collapsed on Aug. 3 and was taken from the field in an ambulance and hospitalized for three days.
Patterson, who has played in more games as an Eagle than anybody on the team, was diagnosed with a brain AVM, or arteriovenous malformation, a prenatal condition in which blood travels abnormally between the arteries and veins.
Coach Andy Reid said Patterson needs about a week of conditioning work to get back into shape. After that, there's a chance he could be cleared by doctors to return to football.
Open season: New 49ers coach Jim Harbaugh said rookie Colin Kaepernick will get his shot to compete with Alex Smith for the team's starting quarterback job. Harbaugh still considers it Smith's spot to lose, but said nobody has earned the position so far. The 49ers also may add an experienced backup.
Extra caution: Packers cornerback Charles Woodson and tight end Jermichael Finley didn't play in their team's exhibition opener against the Browns. Woodson has recovered from a broken collarbone sustained in the Super Bowl, but Packers coach Mike McCarthy elected to rest the 14-year veteran. Finley was out with a minor leg injury.
Extra points: Jaguars veteran quarterback David Garrard, 33, returned to practice after missing more than a week with a sore back. He threw passes and said he hopes to play in the team's next exhibition game. … Seahawks coach Pete Carroll said Russell Okung's left ankle sprain isn't serious, and that the left tackle could be ready for the team's regular-season opener. … The Lions signed free-agent cornerback and former Steelers starter Anthony Madison to a one-year deal. Financial terms weren't disclosed.
