We noted earlier that WWE World Heavyweight Champion Brock Lesnar was backstage at last night’s RAW in Nashville but not used. Dave Meltzer of The Wrestling Observer Newsletter noted that there was more to the story than Lesnar just not being used.

PWInsider reports that Lesnar flew on his private plane to Nashville for RAW earlier in the day on Monday, so he was there.

According to people backstage at RAW, Lesnar was visibly angry about something and one source claimed he walked out of RAW before it ended.

Word is that something happened between Lesnar and WWE but it was not creative related, but something to do with their business relationship. Vince McMahon acknowledged the issue with Lesnar during a SmackDown production meeting this afternoon but did not elaborate on the issue.

Lesnar has already returned home and is not at SmackDown.
