Richard Sherman called out his former college coach after the Seattle Seahawks' 29-3 victory over the 49ers on Sunday night, saying San Francisco coach Jim Harbaugh didn't acknowledge him after the game.

Sherman, who had one of the Seahawks' three interceptions of the 49ers' Colin Kaepernick, was asked by NFL Network after the game what he said to Harbaugh when he ran up to him at midfield and appeared to pat the coach on his 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 apparently was in a feisty mood after the game. In an interview with NBC Sports, he also had a message for the team's doubters.

"There were a lot of pundits and ignorant idiots who thought we were gonna lose this game," he said. "Don't doubt us. Did they not see the last time we played this team?'' That last time was a 42-13 victory in December, also in Seattle. Sherman later said: "A lot of things were said this week that we didn't appreciate. We did what we expected to do."

In July, Sherman told NFL Network that he no longer has a relationship with Harbaugh. The cornerback played four seasons for Harbaugh at Stanford, but after they both left the school for the NFL in 2011, their dealings with each other ended, according to Sherman.

Harbaugh was asked by reporters after the game what he said to Sherman when the two met on the field.

"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."

On Monday, in an interview with ESPN Radio's SVP & Russillo, Sherman again was asked about his relationship with Harbaugh.

"I'm fine. I'm in Seattle. He's in San Francisco. He has a great team. It's fine. I told him good game after the game last night. It is what it is," he said.
