Nutt said Robinson was in the Broyles Center preparing for practice, but began acting disoriented and broke into a cold sweat. The training staff was unable to determine the problem, called paramedics and Robinson was taken to Washington Regional Medical Center to undergo testing.
He remained there late Wednesday evening.
"It wasn't anything that (trainer) Dean (Weber) or anybody could figure out," Nutt said. "He got extremely sick. I don't know if it was the medicine he took or what. I just don't know anything other than that.
"It kind of scared us. He was delirious. He was breaking out into a cold sweat. Dean has never seen anything like it. It's a lot different than anything we've experienced. Usually we know, "OK, he's sick. He's got a virus, throwing up.' But he was breaking out into a cold sweat, talking to himself. He was delirious.
"We're concerned about him and we're going to check him out."
Robinson is listed second on the depth chart behind senior Marcus Whitmore at weakside linebacker for Saturday's game. However, the 6-foot-2, 200-pounder has missed practice time this week because of a groin injury that flared up last Friday.
