The 20-year-old midfielder is one of 38 Chelsea players out on loan this season and was able to make a difference in just his third outing for the League One outfit.
Colkett came off the bench in the 78th minute to level it up in Bristol's eventual 1-1 draw at Bradford City.
After Australian defender James Meredith's headed opener for the Bantams in the 73rd minute, Colkett produced a sweetly-timed left-footed drive in the 86th minute after the ball had fallen kindly for him.

After the match, Colkett said: “I'm absolutely over the moon with it.
“It all happened so quickly. I just hit it as hard as I could.
“I'd love for it to have been the winner. We are playing ever so well lately. We keep drawing, which is better than losing, but if we keep producing performances like that we'll get the three points eventually."
