The Giants released Gillan on Wednesday, Dan Duggan of The Athletic reports.
Gillan spent the past four years with the Giants. He averaged 44.5 yards per punt across 16 regular-season games in 2025, finishing with a 7.3 percent touchback rate and landed 17 of 55 punts inside the opponent's 20-yard line. Gillan will look to join a team in need of a punter.
