Further changes along the sideline are taking place in New York. Shane Bowen‘s defensive coordinator tenure with the Giants has come to an end. 
Bowen has been fired, as first reported by NJ.com’s Art Stapleton. The move comes after interim head coach Mike Kafka‘s second game at the helm. The Giants once again found themselves in position to close out a win yesterday, but they wound up dropping a 34-27 contest in overtime to the Lions. With defensive breakdowns still an issue, Bowen is being replaced. The news is now official, per a team announcement.
On five occasions this season, the Giants have held a lead of 10 or more points but gone on to lose; that includes three blown double-digit leads in the fourth quarter. That trend has led to increasing calls for Bowen to be dismissed. The 38-year-old’s job security was a talking point after the 2024 campaign with owner John Mara publicly criticizing him. As of early September, Bowen joined then-head coach Brian Daboll as a candidate to be replaced during the season.
Kafka took over from Daboll two weeks ago, and he did not make any immediate moves in terms of coordinator changes. Nevertheless, it was reported at the time Bowen was on thin ice. Overall, the former Titans DC’s unit ranks 30th in both points and yards allowed, something which has played a major role in New York’s 2-10 record. Today’s decision thus comes as little surprise.
In a move which many predicted in the immediate aftermath of the Bowen firing, outside linebackers coach Charlie Bullen will take over as interim DC. Kafka has informed the team of Bullen’s promotion, The Exhibit’s Josina Anderson reports. This will be Bullen’s first stint as a coordinator at the college or NFL levels.
After beginning his coaching career at Iowa, Bullen began working at the NFL as a Dolphins assistant. He worked with the team’s linebackers from 2016-18 before doing the same with the Cardinals over a four-year span. Bullen served as Arizona’s outside linebackers coach during the final three years of that tenure before holding that same title with Illinois for the 2023 campaign.
Bullen joined the Giants in 2024, the same time Bowen was hired following the period which saw Don Martindale‘s feud with Daboll lead to his departure. Things have not gone according to plan since that move, with a number of notable defensive additions (such as the free agent signings of cornerback Paulson Adebo and safety Jevon Holland this past spring) not yielding an improved showing in terms of defensive production in Bowen’s second season.
The Giants will play the Patriots in the final game of Week 13. The team’s bye will follow, and then Kafka and Bullen will have a four-game run to close out the campaign. How those two fare in their respective roles down the stretch will be a central storyline for the team and help determine how the coaching staff is handled ahead of the 2026 hiring cycle.
