Scans have revealed Sharks fullback Valentine Holmes suffered a grade two hamstring strain in his teams' trial match against the Broncos on Saturday night.

Holmes was injured in the second half of the Broncos match, however to the relief of Holmes and the Sharks coaching staff, the injury wasn't as serious as first feared.

"It should be right in a few weeks and isn't as bad as we first thought," Holmes said. "I had scans last night and then saw the Doc (Dr George Pitsis) today and it's a grade two strain. When it happened in the game it didn't look too good but it's not too bad.

"I'm not going to rush it and push myself, I want to get it right before I play."

While almost certain to miss the World Club Challenge the status of Holmes for the Sharks round one match with the Broncos is still unknown.

“He just felt his hamstring grab a bit when he jumped and over-extended in trying to score. It’s possibly a three to four-week injury which means he is unlikely to play in the World Club Challenge,” Coach Shane Flanagan said immediately after the game on Saturday night.

The Sharks are expected to name a squad of 20 in the coming days to travel to the UK, with Gerard Beale a potential replacement for Holmes in the fullback position.
