ALLEN PARK -- Linebacker Bobby Carpenter participated in Lions practice today (Thursday) while 19 others were out.

Carpenter, a former first-round pick out of Ohio State, worked out for the Lions on Wednesday after being cut by the Dolphins on Tuesday.

It’s a bye week for the Lions, so some of the players not practicing are just getting rest. Quarterback Matthew Stafford returned for the second straight day.

Linebacker DeAndre Levy, defensive end Turk McBride and running back Kevin Smith were doing drills along the sidelines, but not practicing on the field.

Levy, who said last week his ankle is feeling much better, has only played one game this season. His presence should shore up the defense especially with the loss of LB Zack Follett.

Quarterback Shaun Hill was watching with his left arm in a sling following surgery on his broken arm on Monday.

Others not practicing were: WR Calvin Johnson (shoulder), S Louis Delmas (groin), RB Jahvid Best (toe), WR Nate Burleson (ankle), CB Alphonso Smith, WR Bryant Johnson, DT Andre Fluellen, RG Stephen Peterman, TE Will Heller, DE Kyle Vanden Bosch, DT Corey Williams, TE Brandon Pettigrew, LT Jeff Backus and CB Nathan Vasher (nose/biceps).

Cornerback Paul Pratt who was activated to the 53-man roster over the weekend is back on the practice squad.
