Tennessee Titans' Defensive Coordinator Dean Pees has been taken to hospital during the match against the Indianapolis Colts.
The team announced the news just before half-time, stating "he has been transported to hospital" from the Lucas Oil Stadium.
It is understood Pees experienced a medical issue in the press box during the first quarter.
Titans coach Mike Vrabel said after the that Pees would remain in an Indianapolis hospital overnight for tests, but he sounded encouraged about his prognosis.
"I would say Dean is doing OK," Vrabel said. "They took him to the hospital, they evaluated him, and they are going to keep him overnight for some tests.
"But everything that I heard as of now has been very positive, that he should make a full recovery and be fine with whatever he had going on upstairs."
Pees left the press box in the first quarter in a wheelchair. Vrabel said he called the defense the rest of the day in the team's 38-10 loss to the Colts.
Pees joined the Titans this offseason after coaching previously with the Baltimore Ravens. The Titans were ranked No 1 in the NFL in scoring defense heading into Sunday's game.
