Sherman was heavily involved in the last play of the game, deflecting a Colin Kaepernick pass intended for Crabtree in the endzone which allowed Malcolm Smith to make the interception that saw out a 23-17 win for his side.
Immediately after the match, Sherman added insult to injury by proclaiming that he was the best cornerback in the NFL and would not be beaten by a "mediocre" receiver like Crabtree.
"I'm the best corner in the game. When you try me with a sorry receiver like Crabtree, that's the result you going to get," Sherman told reporters after the game.
"He wouldn't make the top 20 of NFL receivers. If any team had a chance to pick Crabtree, they wouldn't draft him. I was making sure everyone knew Crabtree was a mediocre receiver.
"And when you try the best corner in the game with a mediocre receiver, that's what happens. I appreciate that he knows that now. There has been a lot of talk from him running his mouth about me."
The victory sees the Seahawks progress to Super Bowl XLVIII to face the Denver Broncos.
