Bears sign safety Sherrod Martin to one-year deal

Safety Sherrod Martin signed a one-year contract with the Bears on Tuesday, the Chicago Tribune reports.

Martin, who was cut by the Bears in training camp, re-signed with the team after Antrel Rolle suffered a foot injury in Sunday's win over the Raiders. If Rolle is unavailable for Week 5, Martin or backup Harold Jones-Quartey could see the start at strong safety.
