With top contender Junior Assuncao currently nursing a rib injury, UFC bantamweight champion Renan Barao will instead defend his title against Team Alpha Male's T.J. Dillashaw in the main event of UFC 173 on May 24th in Vegas. The co-main was supposed to be a big heavyweight battle between Junior dos Santos and Stipe Miocic, , but it looks like a welterweight war between Robbie Lawler and Jake Ellenberger will instead take that spot. The final main card bout hasn't been decided as of yet.
Here's what the card looks like right now, but it will obviously change a bit over the next month.
