Bullocks, a second-round pick from Nebraska in 2005, has started 49 games in his career. While he lacks the ability to play solid man coverage, his speed is well-suited for Chicago's two-deep zone scheme.
The Bears chose not to pursue re-signing safety Mike Brown last month, and little has been reported regarding free agent Brandon McGowan.
Bullocks adds depth at his position for the Bears. Few game-changing safeties will be coming out of college in this year's NFL draft. Craig Steltz and Kevin Payne currently round out the Chicago's depth at safety, with Danieal Manning expected to remain at nickel back.
