Stanford quarterback Josh Nunes has been forced to retire from American Football after suffering a "freak" injury in an off-season workout.
Nunes was working out in the gym using the bench press when he dropped a weight on his chest, rupturing a tendon in his pectoralis.
This required surgery using screws to reattach the tendon. However, his recovery will take 12 months and he feels that it is not worth the risk to play football again.
Nunes told The AP: "It's kind of a tough way to go out. Definitely faced a lot of adversity, both with health and football. Obstacles are a part of life and definitely meant to be overcome."
His father added: "The injury shouldn't have happened and we're not sure why it happened. It's not something that could've been prevented. Doctors told us it's rare for quarterbacks. Just a freak accident."
Nunes is to finish his bachelor's degree in management science and engineering in the coming months at Stanford.
