The Chicago Bears have reached a four-year deal with fourth-round defensive end Corey Wootton, Brad Biggs of the Chicago Tribune reports.

Financial terms were not disclosed.

The 109th overall pick in the 2010 NFL Draft, Wootton (6-6, 280) had planned to enter the NFL after the 2008 season, but suffered a torn ACL in the Alamo Bowl game. Despite the severity of the injury, Wootton didn't miss a single game for Northwestern last season. Wootton set a school-record with 49 starts during his 4+ season career, where he was credited with 155 tackles (94 solo), including 38 for a loss, 19.5 quarterback sacks, four passes defensed, and four blocked kicks.

While teams were wary of the state of Wootton's knee, a neck injury during his freshman year may have hurt his draft stock. Wootton was injured three games into his freshman season, and earned a medical red-shirt that allowed him to reach 49 starts.

Woottoon becomes the third of the Bears' five 2010 Draft choices to reach a deal, joining seventh-round offensive tackle J'Marcus Webb and fifth-round cornerback Joshua Moore, who signed earlier this week. Third-round safety Major Wright and sixth-round quarterback Dan LeFevour remain unsigned, but are expected to be wrapped up this month, if not this week.
