Cameron Munster is set to face scrutiny from the NRL's match review committee after being placed on report for an alleged bite in Melbourne's grand final loss.

The Storm five-eighth was racing downfield late in Sunday's 14-6 loss to Penrith at Accor Stadium when tackled by Paul Alamoti.

Penrith centre Alamoti placed his arm across Munster's face as he completed the tackle and his forearm appeared to go near the Storm five-eighth's mouth.

Munster, who was wearing a mouthguard, played the ball and the game moved downfield before referee Ashley Klein blew his whistle.

Klein halted play and turned to Munster and said: "It can't be certain, it's on report. They (the match review committee) will deal with it later…I just saw saliva."

St George Illawarra's Kyle Flanagan was the most recent player to be charged with biting. He was handed a five-week suspension in August.
