Woods appeared to be struggling towards the end of his 3&1 loss with Patrick Reed to European duo Tommy Fleetwood and Francesco Molinari this morning.
The 14-time Major champion was then left out of the afternoon foursomes with claims circling that Woods was injured.
Woods was captured by Sky cameras on the driving range after Europe romped back to go 5-3 up.
And on watching the 42-year-old golfing great, two-time Ryder Cup winner David Howell thinks there’s a problem.
As the pictures were shown on Sky, host David Livingstone said: “There’s Tiger Woods. Not a success this morning. There was something about watching him that was really disappointing.
“After what he did last Sunday, we wanted it to be a Ryder Cup he enjoyed. Looking at him now and looking at his body language, what are you thinking?”
And for Howell, it was the body language that was all wrong.
“He just looked burdened by it this morning. He gave no positive energy to his partner,” Howell said.
“I just wonder if he was struggling with his back a little bit. Was he uncomfortable with his body? He just didn’t look himself at all.
“His demeanour couldn’t have been more different to the Tiger that we love to see.
“He seemed a bit dour, very calm, he was trying to breathe slowly. We know he tries to go through his routine slowly when he’s under pressure but it was almost as if he was doing it too much.
“There wasn’t any energy there. Patrick Reed, who is very energetic, almost seemed to have to dampen down his emotions.
“It seemed Tiger set a low tone for their partnership which was so surprising after his heroics of Sunday.”
