The Bears on Thursday signed two veterans who participated in this week's minicamp on a tryout basis, safety Sherrod Martin and running back Daniel Thomas.

Martin was selected by the Panthers in the second round of the 2009 draft out of Troy. Last season he appeared in 13 games with two starts for the Jaguars, registering 14 tackles, one interception, two pass breakups, one forced fumble and two special-teams tackles.
Thomas has played in 52 games with three starts the past four seasons with the Dolphins after being selected by Miami in the second round of the 2011 draft out of Kansas State.
Thomas has rushed for 1,480 yards and 10 touchdowns on 409 carries and caught 55 passes for 412 yards and three TDs. In 12 games last season, he rushed for 168 yards and two touchdowns on 44 carries and caught 13 passes for 121 yards.
