Kevin Smith: Insurance for Jahvid Best?

Make that two veteran signings for the Detroit Lions. We noted the arrival of offensive lineman Leonard Davis Monday, and the team just confirmed that it also re-signed tailback Kevin Smith from a group of 24 players who worked out for the team during its bye week.

Smith played for the Lions from 2008-10, but the decision to pair starter Jahvid Best with rookie Mikel Leshoure squeezed him out of their 2011 plans. Leshoure's ruptured Achilles tendon was the beginning of a positional breakdown that has continued with Jerome Harrison's brain tumor and Best's latest concussion.

The Lions have been using a combination of Maurice Morris and Keiland Williams in recent weeks. Smith knows their offense well enough to step in right away, but it's not clear how quickly the Lions want to get him on the field or if they view him as insurance against Best's continued absence.

The Lions were off Monday and will return to the practice field Tuesday. Stay tuned.
