But, Lawler doesn't expect a rusty or run-down Nick ... he believes he'll get a prime version of the fighter from Stockton, Cali.
As for Lawler's future (he's lost his last 4 against guys like Colby Covington and Rafael dos Anjos), we asked him if it's possible next Saturday will be the last time we ever see him in a UFC Octagon.
"Nah, it's not possible. I've been doing this for a long time. My body feels good. Just waiting for good fights that get me excited, and this is one of those fights. Nick Diaz is a big name, and this is gonna be a big event."
Robbie Lawler still fighting. Nick Diaz returning. Music to fight fans' ears.
