With Conte in doubt, Bears sign safety Nolan

Needing help because of injuries at the safety position, the Bears signed Troy Nolan on Wednesday, team officials announced.

Starting safety Chris Conte suffered a hamstring injury in last week’s win at Arizona, and he could be questionable to play against Detroit this weekend.

Nolan, who was drafted in the seventh round by Houston in 2009, has 73 tackles and 3 interceptions in 37 NFL games. He had seven starts with the Texans and Miami Dolphins this season.
