Missouri offensive lineman Nate Crawford and defensive ends Charles Harris and Nate Howard are out for the rest of spring practice after undergoing surgeries, as confirmed by the team on Tuesday.

Crawford, a redshirt junior who started eight games last season at right tackle and left guard for Missouri, had a lower back procedure on Monday.

The school announced those setbacks as part of an injury update on Tuesday. Here’s a look at those who are out, limited or expected to practice, courtesy of Scout.com’s Nate Latsch.

The good news for Crawford is that the Tigers are hoping he’ll return during the summer.

Meanwhile, defensive tackle Terry Beckner, Jr., OL Jonah Dubinski and safeties Isaiah Pierre and Tavon Ross were back at practice but limited on Tuesday.

The receiving corps got a lift with the return of Chris Black, Johnathon Johnson and Ray Wingo from injuries they suffered earlier during the spring. Defensive tackle A.J. Logan is also back.
