From an official press release from the Maximum Fighting Championships:
Maximum Fighting Championship lightweight title-holder Antonio McKee will be unable to defend his title at MFC 28: Supremacy due to a knee injury. Drew Fickett, McKee's scheduled opponent for the co-main event, will maintain his spot on the card in a showdown against replacement Matt Veach (15-2). The Fickett-Veach encounter will be a three-round bout contested at a catchweight of 160 pounds.
“I'm disappointed not to be facing McKee for the title but it's only a matter of time until I get my hands on the MFC lightweight belt,” said Fickett.
“It's truly a sign of what some fighters are made out of,” added MFC Owner/President Mark Pavelich. “Drew Fickett didn't hesitate one bit to accept the change in opponent, and Matt Veach showed the amount of courage he's got in taking the fight with Fickett on short notice.”
