The Bears have signed running back Senorise Perry and safety Marcus Trice, both of whom participated in the team's rookie minicamp on a tryout basis.
In a 2012 win over Pittsburgh, Perry became the first Louisville running back to rush for four touchdowns in a game since former Bears back Michael Bush in 2005. The 6-foot, 187-pounder possesses intriguing speed and special teams ability.
Trice began his college career at Oklahoma before transferring to North Texas in 2012. Last season the 5-8, 193-pounder was named first-team all-Conference USA after leading his team with five interceptions and eight pass breakups. He also blocked two punts and one field goal.
To make room on the roster, the Bears waived punter Drew Butler and running back Willie Carter. Butler, the son of Bears' all-time leading scorer Kevin Butler, was released after the team selected Pat O'Donnell in the sixth round of the draft.
