So, here is how you're supposed to defend your goal by any means necessary:
On Sunday, in Germany's Bundesliga soccer game between S.C. Paderborn and Bayer Leverkusen, goalkeeper Lukas Kruse was knocked out after he was struck in the face by a speeding ball.
Kruse was out for a couple of minutes but managed to shake off the pain and continued playing.
Despite Kruse's efforts to finish the rest of the 90-minute game, Leverkusen still beat Paderborn 3-0.
