UFC 131 just got a little more interesting. Now with Brock Lesnar out due to illness, Shane Carwin has stepped up to face Junior dos Santos.
The bout was suppose to be the conclusion fight to The Ultimate Fighter 13 and give either Lesnar or JDS a shot at Cain Velasquez sometime later this year.
Now though, Carwin brings an intriguing matchup to this updated main card.
Who brings home the win at UFC 131?
