Some smart thinking by Ivan Toney saw him score in his first match back following his eight-month ban from football.
The Brentford striker scored 19 minutes into his return with a curling free-kick, after Nottingham Forest had taken the lead through Danilo.
Replays showed that after speaking to one of his team-mates, Toney bent over to move the ball once to his right, before doing so again.
Nottingham Forest player Ryan Yates could sense the danger as he motioned to his goalkeeper Matt Turner that he thought Toney would look to bend the free-kick around the wall into the back of the net.
