UFC light heavyweight Johnny Walker has promised he will put on a show in his main event fight against Jamahil Hill this Saturday.
Walker returns to the octagon for the first time this year in his second consecutive main event to face No.12 ranked contender Hill.
Their fight was supposed to co-headline the Fight Night card, but the main event between Rafael Dos Anjos and Rafael Fiziev was recently moved to UFC 272 in March.
