FYI, Rockhold blasted Bisping on Instagram Tuesday morning … calling the guy “classless” for refusing to shake his hand after beating him on Saturday night.
“I felt it was a classless move on his part,” Rockhold said … “I don’t believe in kicking a man when he’s down.”
Bisping joined the guys on the “TMZ Sports” TV show (airs tonight on FS1) — and said Luke’s completely delusional because he actually tried to shake his hand TWICE.
By the way, Bisping also says he’s not ready to retire just yet because a true champion defends his belt!!!
There’s a lot more — make sure to watch the whole thing tonight on FS1 at 9 PM PT, 12 ET.
