After winning the Player of the Month Award last week, the skipper made it two in two with the latest gong.
He won the award after his 30-yard screamer opened the scoring in the 3-2 away win at Crawley.
It was his second wonder strike in September after his bicycle kick against Scunthorpe the week before.
Clarke said: “I’m really happy to win the goal of the month award.
"Rory Gaffney played a good pass across to me and I was invited to take the shot on and thankfully it went into the top corner.”
He beat Plymouth's Conor Grant and Swindon's Eoin Doyle to the award.
