The accident saw Dan run into a glass door which he mistook for being open and fall flat on the floor in a restaurant, getting gasps from fellow diners because he was chasing a taxi which he had left his wallet in.
Dan now has a big lump on his forehead but joked that he could still remember the Strictly dance routines. Luckily he was able to get his wallet back as the taxi driver had stopped for a cigarette.
On Instagram, he said: "I've done something completely stupid...I ran back out to chase the driver and ran straight into a giant glass door which I thought was open."
He added: "Full deck on the floor, gasps in the restaurant...lump on the head. Thankfully...I still remember the routine."
This may be the first of many Strictly injuries for Dan and other Strictly contestants, you can read the full list here, as the show starts on Saturday as the celebrities meet and are paired up with their professional partners.
Strictly Come Dancing will start Saturday, September 18 at 7.45pm on BBC1.
