After a 2016 season where they went 12-4 and made the playoffs for the first time in 14 years, the Oakland Raiders have been a colossal disappointment this season, and head coach Jack Del Rio may be feeling the heat.

Tim Kawakami of The Athletic reported on Saturday that tensions are growing between Del Rio and Raiders management. He says Del Rio’s status in Oakland is “increasingly a topic of interest” around the NFL. More specifically, he says the front office could be inclined to look into the way Del Rio handles his coaching staff. He also believes Del Rio could lose some pull on personnel and other decisions.

The Raiders are an underwhelming 4-6 this season, Del Rio’s third in charge.
