Stevie Johnson missed his second straight practice Thursday, putting his availability for Sunday's game against the New York Jets at Ralph Wilson Stadium in serious doubt.
"I don't feel as good about him being able to play, but I can't officially rule him out yet," coach Doug Marrone said after practice.
Johnson injured his right groin in a Week 10 loss at Pittsburgh.
Marrone said the team will not call up a receiver from the practice squad, meaning the options for EJ Manuel at the position will be T.J. Graham, Marquise Goodwin, Chris Hogan and Marcus Easley. Rookie Robert Woods has been ruled out because of an ankle injury.
Safety Da'Norris Searcy returned to practice on a limited basis today after sitting out Wednesday because of a hamstring injury.
"I have no issues there. Unless he has a setback during the week, he should be in great shape," Marrone said.
Defensive tackle Kyle Williams (Achilles) was also back as a full participant at practice today after taking his usual rest day Wednesday.
