Jackson had surgery Monday on a broken ring finger on his left hand after suffering the injury in the Rams' loss to the Buccaneers. Despite the injury, Jackson ran for 110 yards to set the franchise rushing record with 7,324 yards in fewer than seven seasons.
"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."
Wide receiver Danario Alexander was a late addition to the injury report, after he re-injured his left knee during Friday's practice. Alexander will require surgery, according to the St. Louis Post-Dispatch.
Alexander has already had surgery on the same knee four times previously.
