Chicago Bears' second-round pick Jonathan Bostic agreed to a four-year contract Thursday.
Bostic is a candidate to fill the void at linebacker created when the franchise decided to break off contract talks with veteran mainstay Brian Urlacher.
Bostic and former Denver Broncos' inside linebacker D.J. Williams are the primary competitors to start at middle linebacker in 2013.
The 50th overall pick in the 2013 draft, Bostic is the fifth of the Bears' six draft choices to agree to contract terms.
He had 237 tackles, 19.5 tackles for loss, eight sacks and five interceptions at Florida.
