A controversial penalty called on Broncos forward Martin Taupau has cruelled the Broncos of a late chance to level the scores in a subsequent 20-14 loss to the Raiders.
With just under four minutes remaining on the clock, Taupau chased through a bomb put up by Adam Reynolds and in the process, accidentally collected Raiders winger Jordan Rapana in the head with his knee.
The collision caused blood to rapidly gash from the head of Rapana who then immediately dropped the ball.
