Cowboys' Christian Matthew: Injures groin

Matthew exited Saturday's preseason game against the Ravens with a groin injury, Todd Archer of ESPN.com reports.

The 28-year-old signed with the Cowboys last month and is competing for one of the final roster spots in the Dallas secondary. A seventh-round pick by the Cardinals in the 2022 Draft, Matthew didn't play in a regular-season game last season after being placed on injured reserve by the Ravens prior to Week 1.
