The Bills secondary might be the most shorthanded it has been all season Sunday when they face the Chiefs in Kansas City.
In addition to Aaron Schobel, head coach Dick Jauron declared Jabari Greer (knee) and Donte Whitner (shoulder) out for the game, leaving the Bills with just seven healthy defensive backs.
Buffalo is particularly thin at the cornerback position where they have Terrence McGee, Leodis McKelvin, Reggie Corner and Dustin Fox, who was promoted to the active roster Friday.
At safety Whitner might not be the only loss as Bryan Scott (knee) is a game time decision. If Scott can't go George Wilson is expected to play strong safety and draw the coverage assignment of perennial Pro Bowl tight end Tony Gonzalez.
"Tony is going to be a tough challenge for our back four and for our entire defense," said Wilson. "He's productive in the passing game and can run block as well so you have to play him evenly in the run and pass."
Wilson is technically a free safety, but has lined up at strong safety before.
"George is versatile and a very smart player and he's got a good feel and he has played there," said Jauron.
At cornerback Leodis McKelvin is expected to make his second career start at right cornerback in place of the injured Greer, with fellow rookie Reggie Corner expected to handle nickel duties in the slot.
McKelvin had a strong second half of play on Monday night after he had to replace Greer in the lineup against Cleveland.
Fox is expected to serve as the team's fourth corner Sunday.
