Former New England Patriots offensive coordinator and quarterbacks coach Bill O'Brien has rejoined the team over a decade after his previous stint.

The ex-Houston Texans head coach spent five seasons as part of Bill Belichick's staff between 2007 and 2011.

During that time, he helped the Patriots to a winning record in each campaign, plus two AFC Conference Championship crowns.

Following a dismal 2022 season that saw the Patriots miss out on the playoffs with an 8-9 record, Belichick is delighted to have O'Brien back on-board.

"I am looking forward to working with Bill again," New England's head coach said. "He is an outstanding coach and an asset to our staff."

The return of O'Brien to the Patriots' staff will raise question marks over the future of Joe Judge, who succeeded Josh McDaniels following his move to the Las Vegas Raiders last year.

O'Brien joined the Patriots in 2007 as a coaching assistant, before holding various positions such as wide receivers coach and quarterbacks coach.

The 53-year-old also spent seven seasons in charge of the Texans, earning four AFC South titles during his tenure.

He also spent time with Penn State, and most recently worked as offensive coordinator and quarterbacks coach with Alabama under Nick Saban.
