Read: Brad Richards May Suffered A Stinger On Sunday

At Backhand Shelf, Jo Innes writes that Brad Richards may have suffered a “stinger” as a result of the hit from Patrick Kaleta on Sunday night.

A stinger, she notes, is when the head moves in ways that it isn’t designed to move.

In regards to how Richards was able to return to the game, she says “the sudden stretch or crush of the nerve fibres temporarily blocks conduction, and you’re left with a combination of pain/numbness/tingling/the inability to move/no sensation. It resolves in short order, and everything starts working again.”

She adds that stingers can have a delayed onset of numbness, tingling and muscle weakness and Richards will probably have exams done over the next few weeks until he is “truly 100%.”
