In 2014, Cutler signed a contract with WWE. He made his debut on the July 3 episode of NXT, losing to CJ Parker. In February 2018, he began teaming with Jaxson Ryker and Wesley Blake as The Forgotten Sons. The trio made their first televised appearance on the August 29 episode of NXT in a backstage segment with general manager William Regal. Cutler and Blake represented the group in the 2019 Dusty Rhodes Tag Team Classic, where they defeated Danny Burch and Oney Lorcan in the first round and Moustache Mountain in the semi-finals before losing to Aleister Black and Ricochet in the final. At NXT TakeOver: XXV, Cutler and Blake competed in a fatal four-way ladder match for the vacant NXT Tag Team Championship, and despite interference from Ryker, the two were unsuccessful in winning. The group entered the 2020 Dusty Rhodes Tag Team Classic, but were eliminated in the first round by Imperium (Fabian Aichner and Marcel Barthel).
On the April 10, 2020 episode of SmackDown, The Forgotten Sons made their main roster debut, defeating Lucha House Party (Gran Metalik and Lince Dorado). On the May 1 episode of SmackDown, they defeated SmackDown Tag Team Champions The New Day (Big E and Kofi Kingston). This led to a fatal four-way tag team match also involving Lucha House Party and John Morrison and The Miz for the titles at Money in the Bank, where The New Day retained. The Forgotten Sons began portraying themselves as American patriots, with Cutler and Ryker highlighting their services in the Marines. However, the gimmick was soon dropped as the Forgotten Sons were taken off television. On the December 4 episode of SmackDown, Cutler and Blake, now known as The Knights of the Lone Wolf, made their return by accompanying King Corbin to the ring as they helped him defeat Murphy. However, on February 4, 2021, Cutler was released from his WWE contract.
