He also attended the NFL Combine and completed all the combine and positional drills. Jones also participated at East Carolina's Pro Day, but opted to only run positional drills for team representatives and scouts. The majority of NFL draft experts and analysts projected Jones to be selected in the second round. He was ranked the fourth best wide receiver in the draft by NFL media analystMike Mayock, the fifth best wide receiver by ESPN, and was ranked the sixth best wide receiver by Sports Illustrated and NFLDraftScout.com.

2018
Following his rookie season, Jones revealed he had played much of the year with a torn labrum in the shoulder, which required offseason surgery. Jones missed much of OTA's during the 2018 offseason due to another injury stemming from an offseason incident and started training camp on the non-football injury list. Jones showed improvement early in the season as his catch percentage rose significantly from his rookie season despite a low-volume passing offense. He caught a 57-yard pass from rookie quarterback Josh Allen in Week 2 against the Los Angeles Chargers that was his new personal record for his longest reception. The pass traveled 63.8 yards in the air, which was also the second longest air distance for a completed pass ever recorded by NFL NextGen Stats since its inception. Jones recorded his first touchdown of the season against the Houston Texans, a 16-yard pass from Nathan Peterman, that briefly gave the Bills the lead. Against the New York Jets in Week 10, Jones caught another touchdown to go with 93 receiving yards, a new career high. He recorded his first game with multiple receiving touchdowns two games later, catching two scores in a 21–17 loss to the Miami Dolphins in Week 13. Jones finished the 2018 season as Buffalo's leading receiver after the team released Kelvin Benjamin. He caught 56 receptions for 652 yards and seven touchdowns.
On March 21, 2018, Jones was arrested in Los Angeles for suspicion of felony vandalism. Jones was involved in an altercation with a man on the 30th floor of an apartment building, with the man seemingly being identified as Jones' older brother, Cayleb. Jones allegedly smashed a window, resulting in cuts on his foot, and tried to jump out, but with Cayleb and police stopping it.
