In a slow week with just two practices the Bears are watching available free agents.

An NFL source said the team has put six players through tryouts at Halas Hall, a group including two safeties and three veteran defensive linemen.

In for a close look at Halas Hall was safety Darcel McBath, a Broncos second-round draft pick in 2009, and fellow safety Tom Nelson, a Hersey product out of Illinois State who spent the last two seasons with the Bengals. The Bears have struggled at safety but there is no indication the team will sign either player.

McBath was one of the Broncos' final cuts in September and he has been on the tryout circuit, recently working out for the Cowboys, Texans and Raiders.

Three veteran defensive linemen also got a look, Chauncey Davis, Keyunta Dawson and Jovan Haye. Davis is a veteran who spent the previous six seasons with the Falcons. Dawson previously played for the Colts. Haye has been with four teams since 2005 and spent the previous two seasons with the Titans. It could be the Bears want to stay up to date with available players for their emergency list.

The Bears also looked at Reggie Stephens, a center from Iowa State who made a pre-draft visit to Halas Hall in 2010. He was a seventh-round pick by the Bengals last year.
