He finished as Baylor's All-Time leading rebounder. He also was the first player ever to reach over 1,000+ points and 1,000+ rebounds in school history.
Gathers was selected by the Dallas Cowboys in the sixth round of the 2016 NFL Draft, based on the potential he showed during his pre-draft workout. In rookie minicamp the team considered playing him at defensive end, but decided to keep him at tight end instead. On September 3, he was released and was signed to the practice squad the next day. He signed a reserve/future contract on January 17, 2017. After a strong training camp and preseason, Gathers made the Cowboys' initial 53-man roster in 2017. However, he suffered a concussion in the preseason, and was placed on the injured reserve on September 4, which made him eligible to return in week 8 at the earliest. Despite practicing with the squad since week 9, after week 13, he was shut down for the season. It was later revealed that he also suffered jaw and neck injuries as well. In 2018, the Cowboys made the unconventional move of keeping him as the fourth tight end to avoid losing him to waivers, even though he was arrested on the eve of cuts for marijuana possession. He was the fourth-string tight end behind Geoff Swaim, Blake Jarwin and rookie Dalton Schultz. In Week 5, he recorded his first professional catch against the Houston Texans. He finished with 3 receptions for 45 yards. On June 14, 2019, it was announced that Gathers was suspended for the first game of the season, after violating the NFL's policy and program on substances of abuse. On August 5, Gathers was waived by the Cowboys.
On August 11, 2019, he was signed as a free agent by the Cleveland Browns. He was placed on the reserve/suspended list on August 31, 2019. He was waived by the Browns on September 10, after being reinstated from the suspension.
