Shane Carwin ends retirement, makes RIZIN debut in open-weight tourney
Former UFC interim heavyweight champion Shane Carwin is making his return to mixed martial arts after a five-year absence.
The 41-year-old Coloradan has signed with the RIZIN Fighting Federation and will make his debut in the second round of the company's open weight World Grand Prix tournament in Saitama, Japan, on Dec. 29.
His opponent has yet to be determined.
Carwin, a former NCAA Division 2 wrestling champion, used heavy hands to blitz his way through the UFC's heavyweight division, columinating in a ferocious knockout of Frank Mir to claim the interim title at UFC 111.
