NEWPORT Gwent Dragons speedster Tom Prydie has admitted his frustration at the timing of an injury that ended his hopes of answering Wales' World Cup SOS.

The 23-year-old will make his comeback in Friday's Guinness Pro12 clash against Edinburgh at Murrayfield after eight weeks on the sidelines with an injury to his left knee suffered in the loss at Leinster.

The timing couldn't have been worse – while five-times capped wing/full-back Prydie was laid up, Wales were down to the bare bones at England 2015.

Dragons teammate Hallam Amos, Leigh Halfpenny, Jonathan Davies, Scott Williams, Liam Williams, Cory Allen and Tom James were all injured, leaving boss Warren Gatland to call up Ospreys ace Eli Walker ahead of the quarter-final with South Africa even though the wing was unfit to play because of a hamstring problem.

"It was frustrating because everyone seemed to be dropping but I don't know if I would have been selected," said Prydie, who also had keyhole surgery on his right ankle over the summer.

"It was more frustrating for me that I couldn't play for the Dragons but these things happen in rugby. It would have been brilliant (to be called up for the World Cup) but it wasn't to be so I have to move on and focus on the Dragons.

"I've been injured and the wingers here have been playing well so it's just about getting back on the field and performing; Wales things come from there so my focus is purely on the Dragons."

Prydie returns to a Dragons team who are starting to step it up after a sluggish start to the Pro12. A European Challenge Cup thrashing of Sale and narrow loss to Castres mean they head to Scotland in confident mood.

"It's similar to last year with Europe as a fresh page and we have performed well," said Prydie, who made 30 appearances last season.

"They boys have been playing really well and it will be good for the squad to get back up to full strength soon. When the likes of Hallam and Tyler Morgan come back we can really push on up the league."

The trip to Edinburgh is a return to the scene of last season's hugely disappointing 45-16 Challenge Cup semi-final hammering at the hands of the Scots.

"It's been mentioned one or twice but it's a new season and a different competition," said Prydie.

"We know that they are a big set piece team and most of their tries have come from being direct. It's a big challenge up front, I am sure Kingsley (Jones, head coach) and the forwards have been working hard and we will want to put our sharp backs into space."
