49ers' Tevin Coleman to Undergo MRI for Ankle Injury, Is in Walking Boot

San Francisco 49ers running back Tevin Coleman was ruled out of Sunday's game after he suffered an ankle injury in Week 1 against the Tampa Bay Buccaneers.  

Coleman later left the locker room in a walking boot and will undergo an MRI on Monday, per Matt Maiocco of NBC Sports Bay Area. 

Head coach Kyle Shanahan told reporters he's "concerned" about Coleman's injury.

The 26-year-old signed a two-year deal with the Niners during the offseason after spending the first four seasons of his career with the Atlanta Falcons. He had six carries for 23 yards and two catches for 33 yards before leaving the game.

Despite primarily serving as the backup to Devonta Freeman in 2016, Coleman scored a career-high 11 total touchdowns with Shanahan as his offensive coordinator. Shanahan went on to become the 49ers head coach, and he has since been reunited with one of his favorites.

With Freeman injured for much of last season, Coleman appeared in all 16 games and made 14 starts. He rushed for 800 yards and four touchdowns while making 32 catches for 276 yards and five scores, marking the first time he topped 1,000 yards from scrimmage in his career.

After a strong 2018 campaign, the 2015 third-round draft pick out of Indiana joined a fairly crowded running back group in San Francisco.

When the 49ers signed Coleman, they already had Matt Breida, Jeff Wilson and Raheem Mostert in addition to the returning Jerick McKinnon, who missed all of 2018 with a knee injury and has since gone on injured reserve after undergoing another knee surgery.

Even so, Coleman entered as the odds-on favorite to receive the bulk of the work in the backfield since he and Shanahan had enjoyed previous success together.

Although the 49ers had plenty of backfield depth before signing Coleman, bringing him in was a significant move with questions surrounding their passing game.

With quarterback Jimmy Garoppolo coming off a season-ending knee injury of his own, there was some thought the Niners would lean heavily on the running game, especially in the early part of the season.

If Coleman is forced to miss time, the team is well-equipped to make up for his absence, with Breida and Mostert being the top candidates to lead the way until he is able to return.
