Sherman made a vital intervention in the closing stages of the match to seal a Super Bowl spot for his side, tipping a Colin Kaepernick pass meant for 49ers receiver Michael Crabtree into the hands of his teammate Malcolm Smith for an interception.
In his comments immediately after the match, Sherman proclaimed that he was the best cornerback in the NFL and slammed Crabtree as a "mediocre" player.
"Obviously I could have worded things better and could obviously have had a better reaction and done things differently. But it is what it is now, and people's reactions are what they are," Sherman told ESPN.
Sherman has also apologised for taking the attention off his teammates' success with his actions.
