Jon Jones defeated challenger Thiago Santos by split decision to defend his UFC light heavyweight title Saturday night at UFC 239 at T-Mobile Arena in Las Vegas.
Two judges scored the bout 48-47 for Jones, while a third judge had it 48-47 for Santos.
Santos appeared to hurt his left leg while kicking Jones in the second round, compromising his movement for the remainder of the fight.
Jones (25-1, 1 NC), 31, was making the second defense of the belt he won by third-round TKO in his rematch with Alexander Gustafsson at UFC 232 in December.
