New England informed Mapu on Tuesday that he will be cut, Mike Reiss of ESPN.com reports.
A 2023 third-round pick, Mapu had one year remaining on his rookie deal. He suited up for all 17 regular-season games in 2025 but handled a career-low 120 snaps on defense, compared to a career-high 254 snaps on special teams. He had 25 tackles (18 solo), five passes defensed (including one interception) and one forced fumble.
