Rajon Rondo didn't get on the team bus with the rest of the Chicago Bulls to travel from the hotel in D.C. to the Verizon Center Tuesday ... but the team insists it has NOTHING to do with his beef with head coach Fred Hoiberg.
TMZ Sports spotted Rondo getting into a private car at his hotel before the Bulls played the Wizards -- while the team bus was parked right outside.
The timing is interesting since Rondo has voiced serious displeasure with Hoiberg over his recent 5 game benching.
