Tennessee Titans star LB Rashaan Evans says he's sorry for uncorking a violent right hook to the dome of a Broncos player ... and he's now vowing to make up for it next week.
If you missed it ... during a play in the 1st quarter of the Titans-Broncos game Monday night -- Denver tight end Jake Butt got into it after the whistle with Evans.
The two tangled up ... and Evans was so heated about being grabbed -- he straight-up threw a Mike Tyson-like haymaker right to Butt's face.
