It depends on (a) how he loses; and (b) what happens in Gus/Rumble. If it's a controversial decision or something weird and flukey (like, Jones breaking his toe like in the Sonnen fight), then yeah I'd be fine with an immediate rematch, probably regardless of Gus/Rumble. If it's a fairly competitive fight, but one that the vast majority agree DC won (for example, a fight like Edgar/Bender 1), and Gus or Rumble wins in impressive fashion, I'd rather see the winner of Gus/Rumble go next with Jones taking one fight before getting a rematch. However, if Gus/Rumble is a shit-show or ends in a weird way, then I'd probably be OK with Jones getting rematch. If DC just stomps Jones, then no.
