San Francisco 49ers rookie Nick Bosa left the practice field on Wednesday after suffering an ankle injury, but it was not believed to be that serious.

That's apparently no longer the case.

An MRI revealed that Bosa's injury is consistent with a "dreaded high-ankle sprain” and that the No. 2 overall pick out of Ohio State will miss the rest of the NFL preseason.

The sprain occurred when Bosa got tangled up with several teammates on a running play. After a few minutes, Bosa was able to stand and walk off the field with the aid of two athletic trainers. He continued to walk to the medical staff under his own power.

This isn't the first time that Bosa has had health issues. The 2017 Big Ten Defensive Lineman of the Year was unable to put together another quality campaign in 2018 and was forced to miss most of his final season with OSU as a result of a core muscle injury. He also missed most of the 49ers offseason program with a hamstring injury. It's becoming clear that San Francisco may just be in for more of the same.

The only thing he can do now is be patient, listen to the trainers, and do everything he can to get back out there with his teammates.
