"Absolutely, I will definitely be out there Sunday," said Jackson, who had two pins inserted into the finger. "The surgery went fine. Everything went well. It's unfortunate it had to happen. It's on the left hand, so it's not a big deal as if it was my right hand."
Alexander has already had surgery on the same knee four times previously.
Questionable are defensive tackle Fred Robbins (toe), defensive tackle Darell Scott (ankle), cornerback Ron Bartell (neck) and offensive tackle Jason Smith (concussion).
