Unhappy triad includes the medial collateral ligament not the lateral. But after watching the injury in slo mo it appeared he did blow out the medial collateral and not the lateral.
I had a patient come in yesterday who had an injury to his MCL and I mentioned that to him. Although in his case I thought it was bruised, not torn.
Either way, still "unhappy" and will require surgery. Hope RG III comes back.
