The latest from around the NFL as the countdown to a Super Bowl 50 matchup between the Panthers and Broncos begins:

• After appearing in and starting in 71 games from 2010-14, 49ers offensive tackle Anthony Davis decided last June to take a hiatus from football, announcing that he’d “be back in a year or so.” Earlier this month, the 26-year-old added fuel to the fire when he tweeted an intention to return to the 49ers. However, Davis – who’s under 49ers control through 2019 – hasn’t yet set the wheels fully in motion on a comeback. “As of right now, I’ve got no notification from the league to say that he has [filed for reinstatement],” general manager Trent Baalke told 95.7 The Game, per CSNBayArea.com. “But that period is still open.”
• In other 49ers news, they’ve hired Jeff Hafley to coach their defensive backs, Alex Marvez of Fox Sports reports (on Twitter). Hafley was in charge of Cleveland’s secondary the past two seasons.
• The Patriots need to invest significant resources this offseason in the offensive line – whether through free agency, the draft or both – in order to keep Tom Brady playing at a high level, writes Christopher Price of WEEI.com. Given the beating Brady took Sunday in the Pats’ 20-18 AFC championship game loss in Denver, Price’s suggestion comes as no surprise. The Broncos hit Brady 20 times, four of which were sacks, and kept him under extreme duress throughout the game.
• The Cowboys will need a new defensive backs coach to replace Jerome Henderson, who took a job in Atlanta. A successor to Henderson in Dallas is unlikely to come from within the organization, according to ESPN’s Todd Archer (via Twitter). That runs contrary to Ian Rapoport’s declaration (via Twitter) earlier Sunday that Cowboys safeties coach Jim Baker will take over for Henderson.
• Jaguars head coach Gus Bradley has promoted three members of his staff, according to Vito Stellino of the Florida Times-Union: Tony Sorrentino has gone from offensive quality control coach to assistant receivers coach; Aaron Whitecotton, who was assistant to the defense, is now the assistant D-line coach; and Mike Rutenberg has shifted from assistant defensive backs coach to defensive assistant.
