Jon Jones retained his light heavyweight title with a unanimous decision victory over Anthony Smith at UFC 235 on Saturday night, overcoming a two-point deduction for an illegal knee to Smith’s head in the fourth round.

Jones (24-1) had little trouble in an expert display of his all-around brilliance against the overmatched Smith (31-14), who had no answers for the likely pound-for-pound champion of mixed martial arts.

Jones dominated on his feet, against the cage, and on the ground until he got in trouble in the fourth round when his knee struck Smith’s head while the challenger was in a downed position. Referee Herb Dean deducted two points from Jones, who apologized to Smith after the bell.

“This MMA thing is really hard,” Jones said. “Some days you’re going to look amazing, and some days at work you’re not going to perform at the level you hold yourself to.”

Jones finished uneventfully and remained unbeaten since 2009, winning a decision for the fifth time in his last seven fights.

Jones has done it all as a lightheavyweight. It may be time to move up to challenge a heayweight. If there is one fight that will get  Jones to move up to heavyweight, it is Brock Lesnar. Jones weighed in on the possibility of a fight with Lesnar, which would come with a blockbuster payday, at the UFC 235 post-fight press conference.
