10:25 PM PT -- Oregon head coach Mark Helfrich issued a statement saying he will punish the players who participated in the chant.
"We are aware of the inappropriate behavior in the postgame," Helfrich said ... "This is not what our program stands for, and the student-athletes will be disciplined internally."
As if beating the living crap out of him wasn't enough, a bunch of Oregon football players taunted Jameis Winston after the Rose Bowl ... by chanting "no means no" while giving the FSU tomahawk chop.
The players -- who included #36 Kani Benoit and #86 Torrodney Prevot -- were celebrating the ass-whooping when they decided to go in on Winston over his rape case.
FYI -- Winston was never charged with the crime and was cleared in an FSU code of conduct hearing.
