Nik LentzNik Lentz will make his Octagon debut in place of an injured Dan Lauzon against fellow UFC newcomer Rafaello Oliveira in a lightweight preliminary matchup at UFC 103 on September 19 in Dallas, Five Knuckles is reporting, citing sources close to Lentz.

Lauzon and Oliveira were picked up by the UFC after Affliction canceled its August 1 “Trilogy” event, where Lauzon was set to fight Chris Horodecki and Oliveira was to meet Takanori Gomi,  and shuttered its MMA promotion late last month. The pair were then booked to fight on the UFC 103 undercard, but a back injury forced Lauzon to withdraw from the fight on Monday.

Lentz (16-3-1), who trains at Minnesota Martial Arts Academy alongside the likes of Brock Lesnar and Sean Sherk, brings a six-fight winning streak into the 155-pound contest, including a notable win over UFC veteran Drew Fickett, though the victory has been tarnished by Fickett’s five-fight losing streak.

A training partner of current UFC lightweight champ BJ Penn, Oliveira (8-1) has won three-straight, including a unanimous decision win in his most-recent bout in April, after suffering his only career loss to Lyle Beerbohm at an October ShoXC event.
