Panthers back-rower Bryce Cartwright could be sidelined for a number of weeks after suffering a suspected fractured leg.

Cartwright will require scans on his ankle after leaving the field in the 15th minute of the game to ascertain the full extent of the injury.

"He's got a plate in his leg from a previous broken ankle so he's got a lot of pain over the top of that," coach Anthony Griffin said in the post-match press conference.

"He's sore and he couldn't play with it obviously. The doctor just wants to get it scanned and see on the joint if there's no damage.

"He went into the game 100 percent fit, I was just talking to him and he doesn’t know either, he's just got a whack on there in a collision somehow."
