The latest NFL coaching updates:

• One day after Patriots quarterback Tom Brady absorbed 20-plus hits in a 20-18 AFC title game loss to Denver, the Pats are parting ways with offensive line coach Dave DeGuglielmo, according to Ian Rapoport of NFL.com (Twitter link). DeGuglielmo, who had been New England’s O-line coach since 2014, was aware he was on the hot seat, adds Mike Garafolo of Fox Sports (Twitter link).
• Former NFL running back Rock Cartwright is the newest addition to the Browns’ Hue Jackson-led coaching staff. Cartwright will work as an offensive quality control coach, tweets ESPN’s Adam Caplan.
• The Giants have interviewed Paul Pasqualoni about their defensive line coach vacancy, per Fox Sports’ Alex Marvez (Twitter link). Pasqualoni held the same position with the Texans last season.
• Marvez reported Saturday that David Walker was set to become the Lions’ running backs coach. That hiring is now official, writes Tim Twentyman of the team’s website. Walker coached Indy’s RBs from 2011-14, including one season under Jim Caldwell.
