Despite being listed as questionable on the injury report, Abraham promises to be in the lineup on Sunday when Atlanta (7-4) visits San Diego (4-7). Abraham, who is tied for third in the NFL with 12 sacks, practiced Friday, but was limited for the third straight day.
"I'm good," Abraham said. "I'll be ready to go."
Linebacker Keith Brooking has also been limited in practice all week with a knee injury and is questionable for Sunday. Several other Falcons are questionable, including kicker Jason Elam (hip), running back Jerious Norwood (rib) and receiver Roddy White (back).
Abraham was already battling injuries to his neck and shoulder when he rushed from the left side against a Panthers double-team and got knocked backward and onto the Georgia Dome turf. He walked off the field without help early in the fourth quarter, but team trainers quickly diagnosed a mild concussion.
Though Abraham lobbied to return, defensive line coach Ray Hamilton wasn't going to risk that his best pass rusher would hurt himself even worse, particularly after Harry Douglas ran back a punt for a 61-yard touchdown and a 38-21 lead.
"I could have, but Harry pretty much canceled that with the punt return for a touchdown," Abraham said. "Ray wanted me in there, but it was the smart thing to do. I had a little head injury, and I didn't want to go in there and get knocked out again."
Abraham's 79.5 sacks since the start of his rookie season with the New York Jets in 2000 rank second among active players. Against the Chargers, Atlanta will face an offense that's allowed just 16 sacks of quarterback Phillip Rivers this season.
