A featherweight bout has been added to the UFC 155 card on December 29th in Las Vegas as Erik Koch meets Ricardo Lamas. 
The UFC announced the bout today and the fight will take place on the preliminary card.
Koch (13-1) is currently on a four fight winning streak and was scheduled to face UFC featherweight champion Jose Aldo at UFC 153. However, he suffered an injury and it appears that Frankie Edgar will be the next title contender for Aldo.
Lamas (12-2) has won his last three fights and is coming off a decision win at UFC on FX 4 against Hatsu Hioki. If Hioki would have won the fight, he would have secured a title shot. Since coming to the featherweight division, two of his three victories are by stoppage, which includes a submission of the night win over Cub Swanson.
UFC 155 takes place on December 29th from the MGM Grand Garden Arena and will be headlined by Junior dos Santos defending the UFC heavyweight title against Cain Velasquez, who he defeated last year to win the title.
