Detroit Lions head coach Dan Campbell cut a frustrated figure after being told by a journalist that one of his players had accidentally leaked an offensive play on social media.

Before their 23-20 victory over the Chicago Bears on Thanksgiving, Lions running back Jahmyr Gibbs shared a photo on his Instagram story which showed teammate Jermar Jefferson stood in front of a whiteboard filled with specific plays.

Fans were quick to spot that the whiteboard was filled with specific offensive plays, though it is unclear whether Detroit actually uses any of them in-game or not.

Regardless, Gibbs, 22, risked exposing team secrets by posting the photo on Instagram – and Campbell was unaware of it up until a press conference on Saturday.

The Lions coach was told by a reporter in that press conference about his player’s actions, which appeared to leave him both stunned and furious in equal measure.

When told about Gibbs’ apparent leak on social media and asked if he needs to remind him to be smart about posting online, Campbell said: ‘Oh, I didn’t know that. I did not know that.

‘Ok, yeah, I need to check on that then. Did not know that.’

Before swiftly leaving the press conference, he added: ‘Yeah, I’d rather our stuff not be out there. Thanks.’

Gibbs is currently in his second season with the Lions after being selected with the 12th overall pick in the 2023 NFL Draft.

The former Alabama college star has been a crucial member of Campbell’s offense in 2024, recording a total of 973 rushing yards and 11 total touchdowns so far, both of which rank in the top five in the NFL.

He has helped Detroit flex its muscles as a major Super Bowl contender by winning 11 of their 12 regular-season fixtures, with the only slip-up coming against the Tampa Bay Buccaneers in Week 2.

Next up for the Lions is a huge showdown with the Green Bay Packers at Ford Field next Thursday.
