Giants Add J.J. McCarthy as Backup QB After Dart’s Season-Ending Injury

The New York Giants traded a 2027 fifth-round draft pick to the Minnesota Vikings for quarterback J.J. McCarthy. The move follows starter Jaxson Dart’s season-ending knee injury in Week 2. Veteran Jameis Winston remains the starting quarterback, with McCarthy slated to serve as his backup while learning the Giants’ offense.

Dart’s injury left the Giants without a clear heir-apparent at quarterback. Winston, who entered the season as a veteran backup, was thrust into the starting role, posting a 11-of-27 completion (111 yards, 1 INT) in a 28-6 loss to the Los Angeles Rams (Week 2) and a 14-of-22 effort (118 yards, no TD/INT) in a 12-7 win over the Tennessee Titans (Week 3). The trade aims to add depth and insurance for the remainder of the season.

When asked whether McCarthy’s arrival challenged him, Winston emphasized personal improvement rather than threat.

Head coach John Harbaugh confirmed that Winston will continue as the starter for the upcoming Week 4 game against the Arizona Cardinals and that the team is “ready to play” while integrating McCarthy into the playbook. Analysts Kyle Long and Jordan Schultz both stressed that McCarthy’s role is explicitly developmental, with Winston retaining the primary quarterback duties.

• “The understanding has to be clear; the messaging has to be clear to [J.J. McCarthy]: he’s here to develop. Jameis [Winston] is the guy and when the guy with the diamonds [Jaxson Dart] comes back, he’s playing quarterback so don’t get it twisted young man.” — Kyle Long, now-cbs analyst

• “The Giants’ addition of J.J. McCarthy is viewed as more of a move to bolster the backup position behind Jameis Winston, not to supplant him.” — Jordan Schultz

The Giants will face the Arizona Cardinals in Week 4, with Winston slated to start and McCarthy expected to continue his acclimation to the Giants’ system. The trade’s long-term impact will hinge on Winston’s performance and any further injuries at the quarterback position.
