NFL teams typically bring in tryout players on Tuesdays -- which is also the players' day off -- to evaluate and possibly sign if the clubs feel those players can better the back end of the roster or as a possible contingency plan for injuries down the road.
Here’s the list of players who worked out on Tuesday for the Chicago Bears:
Brandan Bishop, DB, North Carolina State
Sean Cattouse, DB, California
Rogers Gaines, OT, Tennessee State
Nick McDonald, C, Grand Valley State
Chaz Powell, DB, Penn State
Kheeston Randall, DT, Texas
Tracy Robertson, DT, Baylor
Amari Spivey, DB, Iowa
A strong safety, Spivey started 26 games for the Lions from 2010-12 and posted five career interceptions and seven pass breakups to go with 113 tackles.
