Josh Allen. He finished the game with five catches for 65 yards as the Bills won 24–18. He recorded his second touchdown, also a 22-yard reception, in a week 10, 22–24 loss against the
Denver Broncos. Kincaid overtook the Bills franchise record for most receptions by a rookie, previously held by
Sammy Watkins, during the Bills' 27–21 win over the
New England Patriots. He finished his rookie year with 73 receptions for 673 yards and two touchdowns. In his playoff debut, Kincaid scored a touchdown in the 31–17 victory over the Steelers in the Wild Card Round.
2024 In week 8, Kincaid recorded his first touchdown this season in the 31–10 victory over the
Seattle Seahawks. In week 10, Kincaid suffered a knee injury in the 30–20 victory over the
Indianapolis Colts. He missed week 11's 30–21 win over
Kansas City Chiefs and week 13's matchup against the
San Francisco 49ers despite having a bye week to recuperate in week 12. In the 2024 season, he had 44 receptions for 448 yards and two touchdowns in 13 games.
2025 In week 1, Kincaid was targeted four times, catching all four passes for 48 yards and the Buffalo Bills' first touchdown of the 2025 season during their 15-point comeback against the Baltimore Ravens. He would catch touchdown passes in weeks 3 and 4, the first time in his career scoring in back-to-back weeks. After having his first 100-yard game of the season in a week 5 loss to New England, Kincaid caught six passes for 101 yards and one touchdown in week 9 against the Kansas City Chiefs. He became the second tight end in Bills' history (
Paul Costa) to record multiple 100-yard performances in a single season. Kincaid finished the 2025 season with 39 receptions for 571 yards and a career-high 5 touchdowns in 12 games. On January 23, Kincaid was selected to the

Travis Kelce. Following the season, it was revealed that Kincaid played the entire 2025 season with a
torn PCL, which affected his availability and his snap count throughout the season. ==Career statistics==
