It's Trey's choice. The doctors put him on anticoagulants for six months after the original diagnosis to dissolve the clots. They monitored him closely then cleared him to return. They switched him to aspirin while playing, which prevents recurrent clots in some patients. That didn't work, but he can try it again to see if alternative treatment is more successful a second time. Since he has access to excellent medical care and constant monitoring, his risk is mitigated but it's still there. Most people probably choose to manage recurrent clots with anticoagulants and avoid contact sports, but ultimately, Trey's health is his own decision.
