Star Fremantle veteran David Mundy has suffered a broken leg while riding a bike with his kids.

The 34-year-old sustained a fibular fracture just above his left ankle in the first week of December when a pedal smashed into his leg.

Mundy took part in pre-season training for two weeks after the incident but reported soreness on Friday and was sent for scans that uncovered the fracture.

The club is unsure how long the midfielder will be sidelined, but he requires non weight-bearing immobilisation for at least four weeks.

“Most likely, the fracture is a result of an injury that David sustained whilst riding his bike with his children,” Fremantle football chief Peter Bell said.

“… David is a professional and we are sure he will do everything he can to get his body in the best shape for 2020.

“Given the type of injury, at this stage there are no set time frames for David’s return to football.”

Mundy has displayed impressive durability throughout his career, playing 316 games in 15 seasons.
