According to NFL.com, Sherman was fined $7,875 for unsportsmanlike conduct/taunting during the NFC Championship Game.
After Sherman made his game-sealing pass deflection, which effectively sent the Seahawks to the Super Bowl, he made a ‘choking’ hand gesture toward 49ers quarterback Colin Kaepernick. Sherman’s deflection, which Malcolm Smith caught as an interception, was a key play in the 23-17 Seahawks win at CenturyLink Field. The Seahawks were hit with a 10-year penalty for taunting during the game for his hand gesture.
The fine is not related to the on-field interaction between Sherman and 49ers wide receiver Michael Crabtree. Moments after the pass deflection, Sherman ran over to Crabtree – he smacked Crabtree on the rear and offered the 49er a handshake. Crabtree responded by shoving Sherman in the facemask.
