Magomed Ankalaev vows to dethrone UFC light heavyweight champion Alex Pereira . Pereira (10-2 MMA, 7-1 UFC) retained his title by knocking out Jamahal Hill (12-2 MMA, 6-2 UFC) in Round 1 of Saturday’s UFC 300 main event at T-Mobile Arena. Ankalaev (19-1-1 MMA, 10-1-1 UFC) has had some unfortunate results in recent outings – a split draw in a vacant title fight against Jan Blachowicz , followed by a no contest against Johnny Walker after an accidental knee rendered Walker unable to continue.
