Eager to add depth with two key offensive lineman currently on the mend, the Detroit Lions signed free agent guard Justin Boren to their practice squad on Tuesday according to a report by Tim Twentyman of DetroitLions.com.

The 24-year-old Boren attended both Michigan and Ohio State during his collegiate career, and famously spurned the Wolverines in favor of the Buckeyes in 2008 after a spat with former Michigan coach Rich Rodriguez. Boren was not selected in the 2011 NFL Draft despite being named an All-Big Ten first team selection by the media as a senior.

Though he signed with the Baltimore Ravens as an undrafted free agent later that summer, Boren never once saw the field before being placed on the team's injured reserve shortly before the start of the 2012 campaign. To make room for Boren on the practice squad going forward, the Lions were forced to officially cut ties with 25-year-old defensive tackle Jimmy Saddler-McQueen, who was originally added to the practice squad on Oct. 3.
