Warren made the Pro Bowl as a rookie, just the second Colts tight end to ever do so (John Mackey in 1963). He is also only the second tight end in Colts franchise history to be a PFWA All-Rookie nominee, and the first since Dwayne Allen in 2012. Warren led the Colts in pass targets (112) and was second in receptions (76), receiving yards (817), and receiving first downs (42). He also caught four touchdowns, to go with eight yards and another touchdown on six carries. His receptions and receiving yards were both the most by a rookie tight end in Colts franchise history, and his five total touchdowns were second.
