The Bears traded Marshall and a seventh round-selection in the 2015 NFL Draft to the New York Jets in exchange for their fifth-round draft selection (Adrian Amos) on March 10, 2015. At the time, Marshall said that the Jets would be the last team that he plays for, and that he would retire if cut. From Week 2 to Week 5, Marshall had gained over 100 yards in four straight games. In Week 3, Marshall surpassed the 10,000 receiving yards mark in his career. Starting in Week 9, Marshall recorded six consecutive games with a receiving touchdown. In Week 12, against the Miami Dolphins, he had nine receptions for 131 receiving yards and two touchdowns in the 38–20 victory. In Week 13, against the New York Giants, his 131-yard game gave him his eighth 1,000 receiving yard season of his career. Marshall became the first player in NFL history to have a 1,000-receiving yard season with four different teams. In Week 16, Marshall recorded 115 yards and two touchdowns in the 26–20 overtime victory over the New England Patriots. He finished the 2015 regular season with eight receptions for 126 receiving yards and a touchdown against the Buffalo Bills in Week 17.
