Carlos Ulberg will fight Jamahal Hill in the new co-main event of UFC 303, before Conor McGregor headlines against Michael Chandler.
Former light-heavyweight champion Hill was due to face Khalil Rountree Jr on the 29 June card, but the latter has received a two-month suspension for consuming a banned substance. Rountree preemptively announced the ‘unintentional’ consumption on social media, in a bid to prove his innocence.
