Randy Orton still appears to be unhappy about Brock Lesnar splitting his head open last year

Who could blame him?

Well, this one might seem kind of obvious, but Randy Orton only helps in making it that way.

Last year, Orton took on Brock Lesnar in the main event of WWE's Summerslam, a match that ended in controversy when Lesnar legitimately busted Orton open and caused this bloody scene to close the pay-per-view.

Orton was later diagnosed with a concussion, and he had to have several staples used in order to close the massive gash caused by the elbow.

Well, it's almost a year later at this point, and while Orton has moved on from the program as time has gone by, it still seems like the former 13-time champion isn't completely over what happened at the event. Recently, Orton has taken to Twitter to voice his displeasure in subtle ways about Lesnar and Lesnar light schedule.

Yeah, so if Orton is still venting some frustrations about how that match ended... it's hard to blame him at this point. Orton has spoken out about the match before, and it seems clear that he's probably not happy about that main event at all.

Since that match, though, Orton has won the 2017 Royal Rumble, which resulted in him winning his 13th world championship at WrestleMania 33. If that was paid back from the guys at the top for what happened in the match... well, it still might not be enough in Orton's eyes.
