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'sย AFL 360,ย 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 toldย 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'ย AFL Tonight,ย revealing that the ex-Giant had suffered tendon damage to his hamstring that would require surgery.

โ€œHeโ€™s told friends that heโ€™s torn his left hamstring off the bone and heโ€™s also done damage to his right hamstring,โ€ Ralph toldย AFL Tonight.

โ€œHamstring surgery is normally a 10 to 12-week issue.

โ€œThe confusion is around the fact he was able to stretch the hamstring after this dramatic chase.

โ€œThereโ€™ll be more investigations (on Tuesday) and then potentially surgery later in the week.โ€

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

โ€œThey rely heavily on their even spread and this is going to put more pressure on the likes of (Steele) Sidebottom and (Scott) Pendlebury,โ€ Montagna toldย AFL Tonight.

โ€œTheyโ€™ll have the depth to cover him, but heโ€™s such an important player. Heโ€™s a line-breaker, he hits the scoreboard.

โ€œIf heโ€™s out for the year, thatโ€™s going to be a big blow for Collingwoodโ€™s premiership chances this season.โ€
