Melbourne captain Cameron Smith is rated a 50:50 chance of playing in week one of the NRL finals after recovering well from an ankle injury.

Cameron Smith’s ankle injury is recovering better than expected, making the Melbourne captain a 50:50 chance of playing in the Storm’s opening NRL finals match.

Smith suffered a high ankle sprain late in the first half of their 22-12 win over Brisbane on Friday night at AAMI Park.

The skipper left the field but returned just after half-time to help steer his side to the crucial victory, which sealed their spot in the top eight.

While the prognosis for such an injury is usually at least a week on the sidelines, Storm football manager Frank Ponissi says the signs are good that the Test hooker will be available.

“Cameron has pulled up better than expected this morning after being assessed by the club’s medical staff,” Ponissi said.

“He will continue to receive treatment throughout the week and at this stage is a 50:50 chance to play in the Storm’s first final next weekend.”

Melbourne are waiting for other results from the final regular round of competition to see where they finish on the ladder and who their opponents will be.

They could finish as high as fourth and earn a double chance.
