An E-mail seeking comment was sent to Rogers Friday. E-mail and telephone messages were left with Kennard McGuire, his agent, and a message was also left with Lions spokesman Bill Keenist.
Detroit drafted Rogers out of Texas as the 61st overall pick in the second round of the 2001 NFL draft. He signed a six-year contract following the 2004 season.

He finishing the season with 36 tackles, three sacks and a fumble recovery over six games.
In his career, Rogers has also blocked nine kicks, including eight field goals and one extra point attempt.
