Collingwood veteran Travis Varcoe has suffered a shoulder injury that will require reconstructive surgery.
The 31-year-old was injured during a training drill at the Holden Centre on Monday.
Collingwood performance and strategy manager Marcus Wagner said it was a disappointing blow for the speedy utility.
“The injury is disappointing for Trav, who has put a lot of work in to his pre-season training,” Wagner said
“While Trav will miss some early rounds of the season, we’ll have a better idea of his return date once he’s out of surgery.”

He made 16 appearances in the Pies' AFL team last year but was overlooked for both of the club's finals.
