Alabama may have suffered a massive blow to its 2019 backfield.

AL.com’s Matt Zenitz is reporting that 5-star running back Trey Sanders has suffered a season-ending injury.

“Alabama 5-star freshman running back Trey Sanders suffered a significant foot injury on the last play of the team’s practice Thursday night and is expected to miss the entire season, per sources,” Zenitz tweeted.

That’s obviously devastating news for Alabama, Nick Saban and the offense. Now, the backfield will consist primarily of Najee Harris and Brian Robinson Jr. this year. Jerome Ford and Kelian Robinson will compete to win the third spot on the depth chart.

Sanders signed with Alabama in the 2019 recruiting class. He was ranked as the nation’s No. 1 running back and the nation’s No. 6 overall prospect, according to 247Sports Composite Rankings.

Nick Saban recently praised Sanders’ work ethic during fall camp.

“Trey Sanders is doing really, really well in camp. His work ethic is really good, he’s learning every day,” Saban said on Wednesday. “You know, his attention to detail seems to be pretty good. He’s got some ability that I think may be able to contribute to the team.

“But, again, you know after five practices in one day and pads, we’re not ready to post a starting lineup, we’re not ready to post roles for everybody on the team,” Saban continued. “I think right now everybody’s focus should be: What do I need to do to improve on? What can I do right now today, to improve? So I can have more success as a player I can create more value for myself and I can go earn it. In terms of what we want to try to accomplish personally and together as a team.”

Although just a freshman, Sanders was expected to compete for major playing time in 2019. The three-headed monster of Najee Harris, Trey Sanders and Brian Robinson gave Alabama one of the best and deepest backfields in the nation.
