The Canberra Raiders will be forced to wait for scans on Josh Hodgson's right knee after he left the field in the opening ten minutes of the club's clash against the Cronulla Sharks.

Hodgson was seen limping to the sideline early in the game against Cronulla, before being assisted on the walk back to the dressing rooms by two team trainers.

The English hooker, who has signed with the Parramatta Eels from the start of the 2023 season, is no stranger to knee injuries, and appeared in clear distress during the walk back to the dressing rooms, as well as when he arrived in the rooms and was being assessed.

Fox Sports sideline reporter Matthew Russell confirmed Hodgson would miss the remainder of the game.

"He left the field, he won't be back," Russell said.

"He was clutching the outside of his right knee."

The cameras then showed the trainers performing assessments on the knee of Hodgson, with Cooper Cronk in commentary confirming the tests picked up by the cameras were for a potential ACL injury.

"What we just saw on camera, that was checking the ACL, checking the structure of the knee," Cronk said.

"He has done an ACL before, so let's hope it's not that."

While the original concern was for an ACL injury, and it can't be ruled out until scans are confirmed on Monday, the Raiders are suspecting an MCL injury.

The MCL, if confirmed, would likely leave the hooker out for anywhere between four and six weeks, likely seeing Tom Starling take over as the main man at dummy half in the coming weeks, with a taste of what's to come in 2023 awaiting Canberra fans, when Starling will take over from Hodgson as the Englishman departs to Parramatta.
