A rumored rematch between lightweights Melvin Guillard and Ross Pearson is now official for March and UFC Fight Night 37.

Set for March 8 from London’s O2 Arena, the card features a main event between Alexander Gustafsson and Jimi Manuwa.

Guillard (31-12-2) and Pearson (15-6) met this past October, but the bout ended in a no-contest after “The Young Assassin” delivered an illegal knee to the Brit.

Pearson was deemed unable to continue and the ref was forced to stop the co-main event contest. No word yet if this bout will be in that same role or not.
