Russell Wilson's middle finger might never look the same after the Seahawks' game Thursday ... 'cause he appeared to badly dislocate it after hitting it on a defender's hand.
Wilson was unloading a deep ball in the third quarter of Seattle's loss to the Rams ... when on his follow through, his hand collided with L.A. star Aaron Donald's.
In video of the throw, you can see the force of the impact caused the quarterback's finger to bend awkwardly -- and when he looked down at the digit, it was clearly out of place.
