Jennings suffered a concussion

ORCHARD PARK, N.Y. -- Center Trey Teague and left tackle
Jonas Jennings were held out of practice Wednesday, leaving the
Buffalo Bills potentially short two starters for Sunday's game at
the New York Jets.

Teague's injury is considered the most serious after coach Mike
Mularkey said Wednesday that a scan of the center's left knee
revealed a problem. Without going into detail, Mularkey said the
problem was located just below the joint.

"We thought it was nerve damage, but it's not that," Mularkey
said. "It's not weight-bearing. It's not like he can't push off or
be effective with it. But we want to be sure. It's a long season.
We don't want to test anything that's not sound."

Teague was not at practice. He was hurt in the second quarter of
Buffalo's 31-17 loss to New England last Sunday. Versatile lineman
Ross Tucker practiced in Teague's place.

Jennings said he was feeling better, but was given an additional
day off to recover after being knocked cold, blindsided by Vince
Wilfork with a helmet-to-helmet hit in the third quarter of
Sunday's game.

Mularkey said Jennings was held out for precautionary reasons
and he hopes the player will return to practice Thursday.

Teague and Jennings were both listed as questionable on the
injury report.

Strong safety Coy Wire was also listed as questionable because
of a bruised quadriceps. It's unclear when Wire was hurt.

Veteran Pierson Prioleau practiced in Wire's place. Wire's
injury could further deplete an already banged-up secondary for a
team that opened the season with three consecutive losses.

Wire was starting in place of Lawyer Milloy, who missed the
first three games with a broken right forearm. Milloy has not yet
begun practicing, and the Bills have not provided a timetable when
he might return.

Veteran cornerback Troy Vincent will miss at least two weeks
after arthroscopic surgery on his right knee Monday. He was hurt on
the Patriots' opening drive after his right leg twisted awkwardly
beneath him while making a tackle.

Terrence McGee, a second-year player, will replace Vincent.

Rounding out the defensive backfield are cornerback Nate
Clements and free safety Izell Reese.

"There's no concern," Clements said. "This is a time for guys
to step in and make plays. ... The guys playing behind the starters
are going to get their opportunity, get their chance to show what
they've got."
