Houston Texans v Chicago Bears

The Lions continue to make a significant splash in the free agent market, with the signing of safety Glover Quin making it four signings on the day after Chris Houston (re-signing), Jason Jones and Reggie Bush.

The 27-year-old Quin has spent the last four seasons with the Texans after being drafted in the fourth round by Houston in 2009.  Quin recorded 64 tackles, two interceptions and a sack in 16 games with the Texans last season, piling up 250 total tackles over his four-year NFL career.
