Hull KR's Newton in fitness race

Newton was a NRL Grand Final winner with the Melbourne Storm in 2007

Hull Kingston Rovers second-row forward Clint Newton is battling to be fit to play at St Helens on Friday night.

The Australian has a calf injury but Rovers coach Justin Morgan is hoping the former Melbourne Storm Grand Final winner will pass a late fitness test.

He told BBC Radio Humberside: "His injury has improved dramatically over the last 48 hours and he has a chance.

"If he continues to improve at this rate he'll play but we'll know a little bit more closer to the game day."

Newton picked up the injury during the Robins' 18-10 home defeat against Leeds last Friday at Craven Park and Morgan said he is the sort of player his side needs against St Helens.

Clint is an important player for us but if he's out then I'll have to find a new front rower

"Clint is an important player for us but if he's out then I'll have to find a new front rower because I'll probably have to switch Jason Netherton back to the second row," he said.

Rovers' other main injury doubt is winger Liam Colbon who has a hip injury while stand-off Paul Cooke is already ruled out with a wrist injury.

Chaz I'Anson will deputise for him as the Robins look to end St Helens' 100% start to Super League XIV.
