Another Saturday, another UFC card, another highly consequential main event. An important bantamweight showdown will headline the UFC’s latest edition of their “Fight Island” residency. Former WSOF champion and UFC title challenger Marlon Moraes will square off against Cory Sandhagen , in the latter’s first UFC main event, in a bout with major implications for the 135-pound division.   Add in a co-main event featuring the always exciting Edson Barboza , and the latest matchup for veteran heavyweight slugger Ben Rothwell , and you’ve got yourself the makings of an interesting evening of UFC action.   UFC on ESPN+ 37 takes place Saturday at Flash Forum at Yas Island in Abu Dhabi.
