Matthew Stafford's wife, Kelly, is clapping back at a Lions fan who's trying to stop people from wearing her hubby's jersey at their upcoming playoff game ... calling the proposed plan "sad."
Detroit is hosting its first playoff game in 30 years against the Rams on Sunday ... which means Stafford will make his return to the Motor City with the intention of knocking his ex-team out of the postseason.
Normally, Stafford's Detroit jersey is one of the most popular ones at Ford Field -- even after he was traded to L.A. for Jared Goff before the 2021 season began.
But, one fan is trying to prevent that from happening this weekend ... appearing to say in a social media post this week that the blue and silver No. 9 threads could bring some bad juju to the home team.
"ANNOUNCEMENT," the fan wrote in the Instagram post. "Please don't wear a Lions-Stafford jersey to the game. This is not a time to be cute or funny."
"This is about business and putting the final nail in the SOL coffin. It ain't personal. Just business!"
It didn't take long for word of the planned ban to get around to Kelly Stafford, who slammed the idea in the comment section of the post.
“Well this is sad because it's the completely opposite of how we feel about this city," she wrote, "but Matthew has always been the bigger person and will continue to be that. Praying for an incredible game with zero injuries. ♥️"
The fan ended up responding ... writing back that the hate is only temporary.
"We love Matthew," the Detroit supporter said, "just not this week.😂"
The game is slated to start at 5:15 PM on Sunday ... leaving Lions fans plenty of time to pick their side of the line in the sand before kickoff.
