Alexander Ovechkin isn't exactly known for his fighting, but he has been known to drop the gloves once and awhile.
Back in the 2019 playoffs, Russian rookie Andrei Svechnikov made the wrong decision to 'poke the bear' and he found out real quick what happens when you get the big veteran mad.
Svechnikov was knocked out and did not play in the remainder of the series. The unfortunate thing for the Capitals was this seemed to wake up the Hurricanes, who were down 2-0 in the series and they came back to win.
