Sherman confirmed after the game that Garcon yanked on his dreadlocks while trying to create separation during the first half of Seattle's 27-17 victory.

"I mean exactly what I said," Sherman told CSN Washington.
Even though Garcon didn't call out Sherman by name, Garcon posted this on his Twitter feed on Tuesday morning:
ESPN.com has reached out to Garcon to confirm his tweet was in response to Sherman.
