North Melbourne defender Scott Thompson is in doubt for Saturday's clash with West Coast after suffering a ruptured testicle in his side's loss to the Lions on the weekend.

Thompson copped a heel to the groin in the third quarter, but managed to play out the rest of the game before going to hospital on Sunday afternoon after the Roos returned to Melbourne.

“Scott was hit inadvertently by a player’s heel to the groin region in the third quarter, but battled through,” North GM football Cameron Joyce told the club's website.

“He came off the ground for treatment for about ten minutes, and managed to play out the game. He was monitored by our medical staff throughout the night.

“We planned for him to go straight to the Epwoth after we landed in Melbourne on Sunday afternoon to see a specialist.”

Thompson had a procedure to fix the injury, with Joyce saying the Roos would give the veteran backman every chance to prove his fitness ahead of Saturday's game with the Eagles.

“It was a pretty quick procedure and he was discharged last night,” Joyce explained.

“He’s been back at the club this morning and is hoping to play this week.

“We’ll give him until the last minute to show he’s able to play.”
