Jim Harbaugh snubbed former Stanford player Richard Sherman following the Seattle Seahawks' 29-3 win over the San Francisco 49ers on Sunday.

Sherman ran up to Harbaugh at midfield and gave him a pat on the rear.

"I told him good job, good game, but he didn't give me nothing back," Sherman told NFL Network. "I guess sportsmanship doesn't go both ways."

Sherman said in July that he no longer has a relationship with Harbaugh.

"I didn't realize it was him until he was moving in the other direction," Harbaugh said, according to NFL.com. "He came up and patted me on the back, and I congratulated him, and same with Doug [Baldwin]. I congratulate the Seahawks, they played a hell of a game."
