Shane Carwin

Shane Carwin is the Colorado engineer and NCAA Division II heavyweight champion wrestler who started his UFC career with a string of first-round knockouts. He knocked out Frank Mir in 2010 to win the interim heavyweight title.

At UFC 116 he battered Brock Lesnar for most of the first round but ran out of steam and was submitted in the second. Back injuries limited him after that, and he coached The Ultimate Fighter opposite Roy Nelson before retiring in 2013. CagePotato covered the Lesnar fight and his retirement.
