ALLEN PARK — Surprisingly tight end Tony Scheffler and linebacker Justin Durant were at practice today (Thursday). They were doing individual drills in the part that was open to the media.

Durant, who has missed three games, said on Wednesday he had passed his concussion tests, but he just did exertion work on Wednesday instead of practice.

Scheffler was injured in the Monday night game and didn’t play against the 49ers.

Jahvid Best, who suffered a concussion on Sunday, was not at practice.

Also not at practice was running back Jerome Harrison who failed a physical by the Eagles which nullified the trade that would have sent Ronnie Brown to Detroit.

Wide receiver Rashied Davis (foot) and S Vincent Fuller (elbow) did not practice.

In practice squad moves the Lions brought back fullback Matt Clapp and put James Davis on practice squad injured list. Davis had practiced one day with the Lions before getting injured.
