Crows forward Brett Burton had knee surgery today and will be sidelined for 4-6 weeks.

Burton returned from the Club’s training camp on the Gold Coast last night and saw a specialist this morning after reporting lingering soreness from Saturday’s NAB Cup game.

The arthroscopy repaired some cartilage damage in his left knee.

Crows football operations general manager Phil Harper said Burton was disappointed but remained positive about being ready for the start of the premiership season.

“Brett hasn’t missed a beat with training over the summer and he approaches his rehabilitation with the right attitude, so we hope to have him back on the track as quickly as possible,” Harper said.

“He will be in a race against time to be available for round one but we have faith in our physical performance team to give him the best chance possible of taking the field against Freo."
