Penrith have confirmed NSW State of Origin hopeful Michael Jennings is fit to play this weekend, but are refusing to speculate on whether he will be dumped to the NSW Cup.

Jennings was believed to be sidelined for up to a month with a shoulder injury first suffered against Newcastle in round eight, but he trained strongly on Tuesday to allay any fears about his fitness.

But the dazzling centre – who was considered a certainty to be in the NSW side for Origin I on May 23 if fit – could find himself playing for Windsor Wolves this weekend with coach Ivan Cleary unsatisfied with his recent form.

Jennings was benched early in the second half of Penrith’s heavy loss to Melbourne on Saturday night, with Cleary admitting he was fit to go back on if required.

He came up with three missed tackles and just one tackle break against the Storm, with Melbourne coach Craig Bellamy admitting he targeted the centre’s suspect shoulder.

There are also allegations Jennings was spoken to by club officials following reports he broke team rules by drinking while part of the team’s rehabilitation group on Anzac Day.
