Tony Scheffler diagnosed with concussion

ALLEN PARK, Mich. -- Detroit Lions tight end Tony Scheffler was held out of practice Wednesday after being diagnosed with a concussion, which likely occured late against Green Bay on Sunday.

This isn't Scheffler's first concussion. In 2011, he was taken to the hospital with a concussion following a hit against the Chicago Bears. In 2010, he reportedly suffered a concussion against Green Bay.

Scheffler and running back Theo Riddick were held out of Wednesday's practice due to concussions.

If Scheffler is unable to play, it could lead to an increased role for rookie Joseph Fauria in multiple tight end sets. Or, if Calvin Johnson returns from his knee injury, the Lions could continue to use multiple wide receiver looks with Brandon Pettigrew as the only tight end.

Johnson (knee), right tackle Jason Fox (knee), safety Louis Delmas (knee), cornerback Chris Houston (hamstring) and wide receiver Nate Burleson (forearm) also missed practice.

No one was limited, according to the team's practice report. Burleson, who was out at practice in his jersey for the first time since his injury, said he did some running and catching of tennis balls Wednesday.
