San Francisco 49ers running back Raheem Mostert is making a strong case to remain on the roster. In the preseason win against the Denver Broncos, he had six carries for 58 yards and a touchdown to go along with his two receptions for 42 yards.

On his touchdown run, Mostert said he saw the defense flowing to the left and saw nothing but green grass.

"I knew I had to beat one person and that was the DB, and he was already blocked," Mostert said in a locker room interview after the game. "I was like, 'Alright, on to the next man,' and it was the safety. I was like, 'I definitely got that.'"

The former Purdue Boilermaker said he had a little hesitation when he entered the game Monday night, but that quickly went away after he got into the flow of the game.

The 49ers placed Mostert on injured reserve after he suffered a gruesome broken arm during a Week 9 Monday night game against the Oakland Raiders. Mostert had seven carries for 86 yards and a 52-yard touchdown run in that game.

Mostert said he has a plate in his forearm with an estimated 14 to 16 screws.

"It is honestly an exciting moment, especially coming back from my injury," Mostert said. "Just having to have a little more confidence in myself and believing in myself that I can do this."

In an interview with Matt Maiocco on the 49ers Insider Podcast, Mostert said he takes things one week at a time by proving his worth and helping his teammates.

"I just go out there and try to prove myself and show everyone I can play running back and just give it the best of my ability," Mostert said. That's all I always try to do."

The 49ers have the luxury of having a crowded backfield with Jerick McKinnon, Tevin Coleman, Matt Brieda, Jeff Wilson, and Mostert.

"Because I don't know where I'm going to fall as far as the running back depth, but I just want to just go out there and give it my all."

In nine games of the 2018 season, Mostert had a total of 286 rushing yards from scrimmage and one touchdown while averaging 7.7 yards per carry and 4.2 yards per reception.

Since signing as an undrafted free agent with the Philadelphia Eagles in 2015, Mostert has been with the Cleveland Browns, Miami Dolphins, and the Baltimore Ravens.

In 2016, Mostert signed with the New York Jets and then the Chicago Bears before landing on the 49ers practice squad on November 28, 2016.
