UFC champions Conor McGregor and Max Holloway have taken shots at each other on Twitter on Sunday after UFC 218.
McGregor kicked the exchange off, and Holloway responded in kind:
McGregor took aim with a "sunglasses" jibe in regards to his opponent's condition after their 2013 bout.
Holloway then promptly responded by describing the 29-year-old as a "retired fighter".
UFC featherweight champion Holloway retained his title at Caesars Arena in Detroit on Saturday, stopping Jose Aldo with a third-round TKO in an impressive display.
After the bout, Holloway was asked about the possibility of taking on McGregor for a second time and said he would be happy to face the Irishman, per Kevin Taylor at the Irish Sun:
"Again, like I said last week to everybody who was at my office, who knows if Conor is even going to fight again?
