CHICAGO -- The Chicago Bears agreed to terms on a four-year contract with 2012 sixth-round draft choice cornerback Isaiah Frey, the club announced Wednesday.

Frey was a first-team all-WAC selection for Nevada his senior year, when he had a team-high five interceptions and broke up 21 passes. The 5-foot-11, 190-pound defensive back appeared in 51 games for the Wolfpack from 2008 to '11, and finished his career with 141 tackles, seven interceptions, 38 passes broken up and two forced fumbles.

There is expected to be competition to make the roster at the cornerback position after the club signed veterans Kelvin Hayden and Jonathan Wilhite in free agency, then drafted Frey and Greg McCoy (seventh round) at the end of April. Last year’s starter Tim Jennings was re-signed after fellow cornerbacks Corey Graham and Zack Bowman departed via free agency.

Frey is now the fourth member of the 2012 Bears draft class to agree to a deal, joining second-round pick Alshon Jeffery, fourth-round selection Evan Rodriguez and McCoy, a seventh-round choice out of TCU.

The Bears will conduct their annual rookie minicamp May 11-13 at Halas Hall.
