Collingwood has confirmed Ben Sinclair will require surgery after tearing his hamstring during last night's 11-point win over Essendon in the opening game of the JLT Community Series.

Sinclair, who suffered four separate concussions in 2016, limiting his availability, was helped from the ground by trainers in the third quarter after tackling Bomber Orazio Fantasia.

Magpies general manager of football, Geoff Walsh, confirmed on Friday afternoon Sinclair will be sidelined for an extended period with what is a serious tear.'

“Scans have confirmed Ben has suffered a reasonably serious tear,” Walsh said.

“Surgery, probably sometime next week, seems likely but the precise details of when that might be and how long his recovery might take won’t be known until he has seen the surgeon.

“It’s a tough break for Ben, who has had more than his fair share of misfortune over his time. That said, he is resilient and, of course, everything within his and our power will be put into seeing him back on the field as soon as possible.”

The 25-year-old is no stranger to hamstring injuries, plagued by the issue during the 2014 and '15 seasons.
