Fremantle forward Hayden Ballantyne will miss the rest of the home and away season after rupturing his pectoralis major tendon in Saturday’s 42-point win over Carlton at Domain Stadium.



He will undergo surgery this week after scans confirmed the severity of the injury.



The pectoralis major is a large muscle in the upper chest, fanning across the chest from the shoulder to the breastbone.



Ballantyne suffered the injury late in the first quarter and was subbed off at half-time.

Not the best news for me today, but the good news 4 @clakkasclarke, he might have a chance of beating me in a bench press comp this wk. — Hayden Ballantyne (@Hayden_ballas) July 20, 2015
