SMU offensive lineman Matthew Huhn announced on his Twitter account that his playing career is over.
"This spring I dealt with a medical issue that affected me daily. Due to this issue, the coaching staff and I decided it would be best for me to end my career in football. I want to thank everyone who helped me get where I am, along with SMU fans and supporters. I also want to thank the former and current SMU football staff for the opportunity that I was given. #PonyUp "
