AUSTIN, Texas — Sam Ehlinger being held out of Saturday’s spring scrimmage isn’t the only issue Texas is dealing with on the health front. Following the scrimmage, head coach Tom Herman said Chris Brown has joined the list of safeties who've had to miss practice time this spring.

With Brandon Jones (ankle surgery), Caden Sterns (knee surgery) and B.J. Foster (concussion) already down, Brown missed Saturday’s scrimmage after being taken to a local hospital to be evaluated for what Herman said are, “lung issues.”

“He came in not feeling great,” Herman said. “The doctors want to be cautious. Certainly nothing life-threatening, but needed to get him evaluated at the hospital.”

Herman said he doesn’t believe the issues Brown and Ehlinger are dealing with, “will keep these guys out for too long of a time.”

The Longhorns had relief behind center in the scrimmage with redshirt freshman Casey Thompson and true freshman Roschon Johnson able to fill in for Ehlinger. The picture is cloudier at safety where with Brown, Jones, Sterns and Foster out, Texas only had three scholarship safeties — sophomores Montrell Estell and DeMarvion Overshown and junior Josh Thompson on scholarship healthy — healthy for Saturday.

Help could be on the way, however, as Herman said Foster is improving.

“If he stays on track, symptom-free, hope to have him back Monday,” Herman said.

Keondre Coburn improved to the point that the redshirt freshman defensive tackle was a full participant in the scrimmage. Coburn had been limited in some practices due to a kidney issue, but Coburn’s bloodwork as of Monday had come back to the liking of the medical staff and he’s back in the mix.

Marqez Bimage should join Coburn when the Longhorns get back to work on Monday. The junior underwent season-ending shoulder surgery last November and although he’s been limited in practice to this point, Herman expects the Brenham product to “be able to be live contact” in some form or fashion.

Monday should also mark the return to practice as a full participant for Bru McCoy, who missed the scrimmage. The true freshman and former five-star prospect has been dealing with a shoulder issue that’s forced him to be a non-contact participant in practice of late.

“If everything progresses the way we think, we think Monday he should be back,” Herman said.

The wide receiver group does, however, have Devin Duvernay back on the field. Although his reps were limited (20-25), Herman said Duvernay scrimmaged on Saturday and has been back at practice in recent days after recovering from a stress reaction in his pubic bone.

There remains no update on the status of true freshman linebacker De'Gabriel Floyd. Herman said the All-American Bowl participant underwent an MRI Friday afternoon for a neck issue relating to stingers he suffered in high school that’s prevented him from being involved in contact portions of practice.

Herman, who said he’s hopeful the results of the MRI will come back soon, said Floyd has already had a bone scan to rule out a stress reaction or fracture or any vertebrae issues. The plan now, according to Herman, is to use the MRI to begin looking at the spinal column, “to see what’s going on in there.”

Along with Ehlinger, Bimage, McCoy, Floyd and the safeties, redshirt freshman offensive lineman Christian Jones missed the scrimmage after rolling his ankle in practice on Monday. Jones returned to practice after the injury, but Herman said the days following the injury revealed it was worse than anyone thought initially and led to Jones being diagnosed with a high ankle sprain.

Finally, defensive lineman Rob Cummins earlier this week aggravated a knee injury that forced him to miss the entire 2018 season. Herman said the sophomore who has bounced back and forth between defensive line and tight end in his brief career with the Longhorns “chipped a little bit of articular cartilage off” during Wednesday’s practice and is set to undergo arthroscopic surgery.
