The USC legend stopped short of saying that this week ... but the former superstar running back did acknowledge he's hearing rumors it might actually go down!!!
"I don't want to put nothing out there," Bush said on Tuesday's The Pat McAfee Show ... "You know, I've heard conversations and things."
Of course, Bush was just reinstated to USC after he was banished for 10 years for accepting improper benefits during his time as a Trojan -- and many have wondered if his relinquished Heisman Trophy could follow suit.
