COLLINGWOOD star Adam Treloar is set to be sidelined until late August after a meeting with a specialist on Tuesday confirmed he has damage to both of his hamstrings.

Scans have revealed Treloar has tendon damage to the hamstring in his left leg, which will require surgery later this week. The gun midfielder also strained the hamstring in his right leg, which amounts to close to two months out of the side.

The injuries occurred when he was attempting to burst clear of Carlton's Lochie O'Brien along the member's wing boundary of the MCG in the last quarter of Sunday's game.

Magpies football manager Geoff Walsh described the dual hamstring injuries as a "freakish occurrence".

"Adam stumbled, his left leg locked and before he tumbled to the ground his left leg stretched beyond its limit. It seems that he strained his right leg on the way down as he tried to compensate for the force pushing through his left," Walsh said in a statement. 

"It is certainly highly unusual, to injure both hamstrings at once. No-one can recall it happening before in football. 

"Still, Adam is a fantastic professional and we have no doubt that he will commit himself to the most thorough recovery possible.

"As to what the immediate future holds, we'll know more after the surgery and his rehabilitation begins."

Depending on how quickly he recovers, there is the very real possibility that Treloar could be ruled out for the rest of the season or he could come back and play on the eve of the AFL Finals.

Treloar has played 134 of a possible 144 matches since 2012 and 56 of a possible 57 for Collingwood after crossing to the Holden Centre from Greater Western Sydney at the end of the 2015 season.
