Striker Jon Walters handed Ireland manager Giovanni Trapattoni a scare when he hobbled off the training pitch in Malahide today.
The Stoke frontman, who sat out yesterday with a back problem, was hurt in a collision with Shane Long towards the end of this morning's session and needed treatment on the pitch.
He was eventually able to walk to the coach as he and his team-mates headed back to the hotel and his ankle will be assessed over the next 24 hours, although the Ireland medical staff are hopeful there will be no lasting damage.
However, goalkeeping coach Alan Kelly later revealed sought to play down the incident. the medical staff are confident there is no lasting damage.
"It's a bit of a bang. He sort of stepped across the ball and Shane Long came in and hit the nerves on the outside of the leg, so it's really just an impact injury.
"I think he'll be okay. It's not a twist or anything like that, just an impact injury."
After the initial burning went, he got up and got on with it. He's a tough lad, Jon."
Walters had lengthy treatment on the pitch, but was able to walk back to the team coach.
"Obviously after something like that, he would be assessed, but he was okay. Just talking to him there, he seemed to be getting over the initial shock of it, really.
"He'll get a bit of ice and as I say, he's a big, tough lad, Jon, and I think he will be okay."
In better news, goalkeeper David Forde and midfielder Glenn Whelan were both able to train today as Trapattoni presses ahead with his preparations for Friday night's World Cup qualifier in Sweden.
