Charlton have made their second signing on the eve of the transfer deadline by snapping up Joe Anyinsah.
The former Carlisle winger, 25, has been training with the Addicks as a free agent in recent weeks and has now joined Dagenham forward Paul Benson in signing for the Addicks.
"We're pleased to agree a deal with him," said Parkinson.
"He turned down a contract with Carlisle and had a few other offers over the summer, but then he picked up a slight injury while he was training on his own.
"He was therefore a little bit behind with his fitness, but he's been working hard with us. He can play either up front or wide right so it adds to our attacking options."
