Sydney star forward Lance Franklin will be fit and firing for the AFL’s opening round, Swans general manager Tom Harley has confirmed.

Franklin sustained a heavy concussion when knocked unconscious in a collision with teammate Gary Rohan just minutes into the Swans’ pre-season win over Greater Western on Sunday.

Swans co-captain Keiren Jack suffered an abdominal injury and was taken to hospital along with Franklin.

However, Harley said on Monday both stars would be fit to play in the Swans’ campaign opener against Essendon on April 1.
