Brock Gutierrez joins the Lions after spending the past two seasons with the San Francisco 49ers. He was the starting center and played in all 16 games for the 49ers in 2004.

During his eight NFL seasons, the 6-3, 304-pounder has played in 98 games with 23 starts. He began his career with the Cincinnati Bengals as an undrafted free agent in 1996 where he played through 2002.
