FOXBOROUGH, Mass. (AP) – The New England Patriots resumed their coaching staff shakeup Tuesday by hiring Scott O’Brien as special teams coach and reassigning two assistants.

Bill O’Brien moved from wide receivers coach to quarterbacks coach, while Josh Boyer went from defensive coaching assistant to defensive backs coach.

New England is still without an offensive coordinator, wide receivers coach and tight ends coach.

Since the Patriots season ended with an 11-5 record but without a playoff berth, they’ve lost four assistants.

Josh McDaniels went from offensive coordinator and quarterbacks coach to head coach of the Denver Broncos. Brad Seely moved from special teams coach to assistant head coach and special teams coach under new Cleveland coach Eric Mangini. Dom Capers went from secondary coach and special assistant to Patriots coach Bill Belichick to defensive coordinator in Green Bay, and Pete Mangurian left as tight ends coach to become offensive line coach in Tampa Bay.

The Patriots also have hired Floyd Reese as senior football adviser and Nick Caserio as director of player personnel after losing vice president of player personnel Scott Pioli to Kansas City as general manager.

Scott O’Brien was special teams coach the past two years for Denver, the fourth NFL team he’s served in that position. His first stop in that job was under Belichick in Cleveland from 1991-95. He moved to Baltimore and Carolina before serving in 2005-06 as assistant to head coach Nick Saban with the Miami Dolphins.

Bill O’Brien began his NFL career as an offensive coaching assistant for the Patriots in 2007. He had spent the previous 12 seasons as an assistant at Georgia Tech, Maryland and Duke.

Boyer became a coaching assistant with the Patriots after serving as defensive coordinator at the South Dakota School of Mines in 2005.
