ALLEN PARK — Cornerback Bill Bentley, who injured his shoulder against Philadelphia, was back at practice today (Thursday) at least for the portion open to the media.

  Calvin Johnson (knee) who wouldn’t have participated on Wednesday if the Lions practiced was on the field for the media portion.

 Missing from practice Thursday were Cliff Avril (back), DeAndre Levy (hamstring), along with Jacob Lacey and Amari Spievey who have concussions.

Also, Lions cornerback Drayton Florence tweeted Thursday that he expects to be back at practice next week. He broke his right arm in the game against the 49ers and was placed on injured reserve with the ability to return.
