It's been tough mentally and physically says midfielder as injury sees him miss Euro action
The Crystal Palace loanee was on the end of a foul by Joel Ekstrand that resulted in him being substituted and brought the Hornets’ defender a yellow card.
The challenge has left Jonny with a groin injury and he’s had a scan and seen a specialist today.
The 21-year-old is disappointed to be on the sidelines again only having just returned to the side after two weeks out.
“I’ve had a few injuries since I’ve been here and it’s been tough mentally and physically. It can grind you down,” Jonny told the Club website.
“I’ve not really been able to have a full week of training since I’ve been here because I’ve had to manage my fitness during the week.”
Wales take on Belgium in Brussels on Friday and Jonny will be a frustrated spectator.
“It’s always disappointing to miss out on games. It’s exciting times for Wales. It’s probably our best chance to qualify in a while,” he added.
“We’ve had two wins and a draw against a good Bosnia side. All the home nations have started well and we will be looking to qualify.”
