QPR boss Redknapp angrily hit out at Fortune and referee Chris Hoy last night for failing to see what he thought was a blatant foul on his goalkeeper in the 2-1 defeat at Loftus Road.
Fortune backed in to Green as he came to collect a ball that had looped up off Armand Traore and the R's stopper duly dropped the ball in to his own net.
Redknapp branded Foy's handling of the situation as "awful", but Clarke thinks the referee was right to let the goal stand.
"I didn't think it was a foul," Clarke said.
"I was confused. I just saw the ball go up and then in the net. I've seen it on the video and I don't think he has done a lot wrong. I didn't think it was much of a foul to be honest.
"That's why he's there and that's why we pay him all that money."
