Seahawks running back Marshawn Lynch won’t be saying “thank you” to the league office this week. (He may instead be using a different two-word expression that ends in “you.”)

Per a league source, Lynch received a fine in the amount of $11,050 for his backward dive while grabbing his crotch into the end zone at the tail end of his career-long 79-yard touchdown run. Lynch wasn’t flagged for the move, which was deemed to be unsportsmanlike conduct.

It’s the same finisher Lynch applied nearly four years ago, at the tail end of his “Beastquake” run against the Saints in the playoffs. Monday’s edition of PFT on NBCSN included a split-screen of the eerily similar runs with the identical endings.

In the 2010 playoffs, Lynch was neither flagged nor fined for the move. Last year, the NFL fined Patriots cornerback Logan Ryan $10,000 for doing the same thing.
