Collingwood president Eddie McGuire has provided an update on star midfielder Adam Treloar's double-hamstring injury sustained during the club's 20-point win over the Blues on Sunday.

Speaking on Fox Footy's AFL 360, McGuire confirmed that the silky Magpie may be sidelined for up to 10 weeks.

"Today he's had scans. He'll see a surgeon tomorrow, we believe one is worse than the other... you're always fearful but I'm also hopeful," McGuire told AFL 360.

"I'm hopeful it's an 8 to 10 at worst. It's unheard of."

Jon Ralph broke the news earlier today on Fox Sports News' AFL Tonight, revealing that the ex-Giant had suffered tendon damage to his hamstring that would require surgery.

“He’s told friends that he’s torn his left hamstring off the bone and he’s also done damage to his right hamstring,” Ralph told AFL Tonight.

“Hamstring surgery is normally a 10 to 12-week issue.

“The confusion is around the fact he was able to stretch the hamstring after this dramatic chase.

“There’ll be more investigations (on Tuesday) and then potentially surgery later in the week.”

Former St Kilda great Leigh Montagna also weighed in on the Pies' cruel blow, saying the loss off Treloar hurts their premiership chances.

“They rely heavily on their even spread and this is going to put more pressure on the likes of (Steele) Sidebottom and (Scott) Pendlebury,” Montagna told AFL Tonight.

“They’ll have the depth to cover him, but he’s such an important player. He’s a line-breaker, he hits the scoreboard.

“If he’s out for the year, that’s going to be a big blow for Collingwood’s premiership chances this season.”
