Charlton manager Phil Parkinson is set to dip into the loan market to solve his right-back crisis ahead of Saturday's trip to Carlisle.

Frazer Richardson is struggling with a thigh problem and his natural replacement, youngster Chris Solly, has suffered a knee injury in training which required surgery.

"Frazer has had a few knocks and I'd be surprised if he makes it," said Parkinson.

"He's the kind of player who wants to play all the time but it might be a risk to play him.

"Chris had an operation and he'll be out for three months so we're struggling a bit.

"There's a possibility we could be getting someone in on loan before Carlisle and it's something we're working on now as we haven't got a right-back in the squad."
