With the status of starting safety Chris Conte very much in question with a hamstring injury, the Bears are expected to sign veteran Troy Nolan today, according to a league source.

Selected in the seventh round of the 2010 NFL Draft out of Arizona State, Nolan started six games in his first two seasons with the Houston Texans. After spending some time with the Miami Dolphins earlier this year, Nolan returned briefly to the Texans and started one more game. For his career, he has 93 tackles, 1 1/2 sacks, nine passes and three interceptions.

With veteran Craig Steltz placed on injured reserve a few weeks ago, the Bears have been thin at the safety position. Other than starters Conte and Major Wright, Anthony Walters is the only other safety on the roster. Walters filled in for Conte Sunday and finished with three tackles.

At the NFL Combine, Nolan was measured at 6 foot 2 inches, and he ran the 40-yard dash in 4.65 seconds.

At Arizona State, Nolan was known for making big plays. In two seasons there, he had five defensive touchdowns.

UPDATE: The Bears confirmed that Nolan has been signed.
