Rich Campbell and Dan Wiederer discuss the Bears' first OTA of 2014.

The Bears waived tackle Rogers Gaines on Thursday. The undrafted free agent out of Tennessee State joined the Bears practice squad as a rookie last Sep. 24.

Gaines' departure leaves the Bears with one vacant roster spot. And as of early Thursday afternoon, they still had not made a transaction involving receiver Domenik Hixon, who tore his anterior cruciate ligament in Tuesday's organized team activity.
