49ers sign CB Marcus Cromartie to practice squad, waive TE Xavier Grimble

The San Francisco 49ers made a small practice squad roster move on Tuesday. They announced the signing of cornerback Marcus Cromartie to the practice squad, and waived tight end Xavier Grimble to make space.

The 49ers now have two defensive backs on the practice squad, with Cromartie joining Chance Casey. The team previously had cornerback Leon McFadden on the squad, but he was promoted to the active roster after Chris Cook was placed on injured reserve.

Considering the 49ers also brought in a pair of cornerbacks for workouts, it is very clear that the team sees the depth issues at the position. They currently have five cornerbacks on the roster, including Perrish Cox, Chris Culliver, Dontae Johnson, Leon McFadden, and an injured Tramaine Brock. They dressed four cornerbacks last Sunday, resulting in Craig Dahl getting extra work in their sub-packages.

Cromartie (6-0, 195) was originally signed as an undrafted free agent by the San Diego Chargers on April 27, 2013. He was waived by the Chargers on August 31, 2013, and signed to the team's practice squad the next day. Cromartie was later promoted to the Chargers active roster on December 17, 2013, where he remained for the rest of the season. He was then waived by San Diego on September 23, 2014, and signed to the Cleveland Browns practice squad on October 29, 2014. Cromartie was released by Cleveland on October 30.

A 23-year-old native of Mansfield, TX, Cromartie played collegiately at Wisconsin, where he appeared in 39 games and registered 113 tackles, 16 passes defensed, one interception, one forced fumble and one fumble recovery. As a senior, Cromartie earned All-Big 10 honors.
