According to Yahoo Sports' Kevin Iole, who receives letters and comments regularly in his MMA mailbag, Cain Velasquez' UFC 121 victory over Brock Lesnar got a lot of mixed martial arts fans talking.

In fact, one letter (entitled "Illegal blow led to Lesnar's demise") caused enough stir for Iole to lead off his sports column the fan's comments:

"Has anyone reviewed the tape of the Brock Lesnar-Cain Velasquez fight Saturday at UFC 121 and looked at what happened with 2:17 remaining in the fight? Velasquez visibly punches Lesnar in the back of the head at that point. Lesnar was not going down until this punch landed," MMA fan Ashley Graham, from Springfield, Illinois, wrote in her letter to Iole?which ran in his online column on October 25.

"There were no replays after the fight. Lesnar was clearly still able to function before this illegal blow. As soon as he was hit, his knees buckled and he fell to the ground and grabbed the back of his head, then was just trying to protect himself.

"Will this be reviewed? Lesnar should have been given time to recover as UFC rules grant. There was nothing mentioned and no replays shown. Will Lesnar get his title back and his record corrected and will there be a rematch as a result of this foul?"
