Choplick's arm seemingly gave out as he grabbed it in pain despite getting the ball down to the bag.
Considering his history with a pair of Tommy John surgeries, it immediately appeared to be an injury that could shut down the 6-foot-8, 261-pound redshirt freshman for the year, if not his career.
But OU head coach Sunny Golloway said that is not the case.
"I just got a report saying good news on Choplick," Golloway said. "So, I don't know exactly what that means, but [it's a] strained muscle. So, that's really good news. Really good news."
In fact, Choplick was active at practice Wednesday not more than 24 hours after suffering the injury.
From here, they'll simply rest him up in the same manner they have with crafty lefty Dillon Overton, who's been out with the same injury, and he'll be out for some time but not the longevity of the season.
"Not if it's just a strained muscle," Golloway said. "Let's do it like we're doing with Dillon. Let's go week by week."
That's a positive diagnosis considering how much OU could need the depth of its pitching staff down the stretch.
