This is the biggest moment in the history of the beef. At the time, it didn't seem like a big deal. Before his title shot with Shogun, Jones did a 20 minute interview with Ariel Welhani on a number of different topics, one of which being, then teammate Rashad Evans. He noted that he thought Rashad would come back well from the injury and that he wanted his blessing before he took the title shot.
Then there was the part that made everything a little sticky. Welhani asked Jon about fighting Rashad because if Jones beat Shogun he'd be the title holder. A fight between the teammates could be called for by UFC president Dana White. His response was if that's what Dana White asked for, he would fight him. But Jones reiterated that he wouldn't want to fight him and it would be awkward for them both.
That's a far cry from saying, "I wanna fight Rashad," but the statement still irked Evans because they vowed to never do it. From that moment on the relationship was never the same.
