Unfortunately, as Tomas was showing off and sliding into home, everyone heard a loud pop. When he tried to get up, he was unable to put any weight on his right foot. Luckily, one of the team members was a paramedic and was quickly able to diagnose a torn calcaneal tendon. If the calcaneal tendon was no longer attached to the bone, which muscle would not be able to contract or relax support weight on his foot?
