Sherman started jawing with Redskins offensive tackle Trent Williams after the Seattle Seahawks' 24-14 win over the Washington Redskins, the altercation ending with Williams violently pushing his right hand into Sherman's face.
Sherman reacted by putting his hands up and offering a taunting smile as Williams was pulled away by several Redskins teammates. FOX cameras later showed Sherman waving goodbye to Williams -- and presumably the 2012 Redskins, who were eliminated from the playoffs in Sunday's wild-card loss.
Sherman later tweeted he didn't hold anything against Williams: "Received a very classy text from @TrentW71. Great player! This is an emotional game no ill will either way. Have a great Pro Bowl! Well deserved."
This isn't Sherman's first notable postgame encounter with an opponent. Back in October, he trash-talked Tom Brady after a Seahawks win over the New England Patriots. Sherman let the world know about the encounter by tweeting a photo of him yelling at Brady, accompanied by the text, "U mad bro?"
Sherman won't need social media to publicize his latest postgame adventure. Sherman is giving Cortland Finnegan a hard run for the title of the NFL's preeminent pest. And we'd guess he loves it.
UPDATE: Williams later issued a statement through his agent, Ben Dogra: "I want to take this opportunity to apologize for my actions that took place following tonight's game. It was a hard fought game between two great teams and I let my emotions get the best of me. To Richard Sherman, the Seahawks, Mr. Daniel Snyder, Coach Shanahan, Mr. Bruce Allen, my teammates, and all the fans ... I am truly sorry. I feel as though I've taken many strides to be a better person this season and this is not how I wanted it to end. And for that, I apologize for my actions."
