Santos, 33, has gradually moved down the scale since beginning his
career at light heavyweight. The
Chute Boxe fighter propelled himself into title contention in
his 170-pound debut, drubbing Dream champion Marius
Zaromskis in June 2010. Santos, the husband of Strikeforce
women’s 145-pound ace Cristiane
Santos, was last seen in January, when he was forced to submit
to a second-round armbar from Nick Diaz.
Only 21, Mein steps onto the big stage with nearly 30 bouts under
his belt. The Lethbridge, Alberta, native has gone 22-7 with 19
finishes since turning pro at 16 years old, and holds victories
over UFC veterans Joe Riggs and
Burkman. Most recently, Mein outpointed Zaromskis after three
rounds in the main event of the inaugural Score
Fighting Series show on June 10.
