BRISBANE Lions draftee Toby Wooller will miss up to 12 weeks after undergoing surgery on his left ring finger on Tuesday night.

Wooller, taken by the Lions with pick 41 in last year's NAB AFL Draft, injured a tendon on the finger in a training mishap last week.

The key forward will miss between 10 and 12 weeks.

The Lions have had a great run with injuries during the pre-season with just Marco Paparone (sciatic nerve) and Sam Skinner, who ruptured his ACL last year, unavailable.
