“I absolutely expect a reaction from Jed about this,” Mark Scannell said.  He was one of three fans that helped get the banner flying.

The banner read, “JED & 49ERS SHOULD MUTUALLY PART WAYS” as it flew above Levi’s Stadium.

The wording pokes fun at the way the team parted ways with former head coach Jim Harbaugh.

“They weren’t very transparent in the process, so we thought it would be kind of funny to poke fun at him,” banner co-creator Graham Grealish said.

The banner sent a strong message.

“We didn’t want to come off as whiny fans, but we felt the message was pretty strong, but still respectful at the same time,” banner co-creator Jack Harrington said.

Fans quickly snapped pictures of the banner and shared them on social media.
