City face Charlton tomorrow, Watford (A) on Tuesday, Forest (A) next Saturday and then Blackpool at Ninian Park on the following Tuesday.
"The international break has worked to our advantage this time, with most of our players having not gone away with their countries," Jones told the Echo.
"The Scotland crew were all here as were the under-21 lads such as Ross McCormack and Joe Ledley, who is injured and will be out of tomorrow's fixture. It means that, apart from Joe, we should all be rested and fresh-legged tomorrow.
"But the other bonus has been that Steve McPhail was carrying a knock and that has had time to recover.
"So, all in all, it has not been a bad couple of weeks for us on that front.
"The break will have done us the world of good as we have had a heavy fixture schedule and couple of players were not 100 per cent fit."
Charlton are without Zheng Zhi but have been boosted by the return of Nicky Bailey for the trip.
China international Zheng underwent an operation on a foot injury on Wednesday and has been ruled out of action for at least two months.
Fellow midfielder Bailey limped off shortly after opening the scoring against Ipswich a fortnight ago with a hamstring injury, but he has managed to get fit over the international break.
Matt Holland replaced Bailey in the 2-1 win over Town and will now come in for Zheng.
Elsewhere, Svetoslav Todorov hopes to shake off a knock and fellow striker Izale McLeod will travel after almost eight months out with knee ligament damage, although he is not likely to be risked.
Harry Arter (Achilles) is back in training and could be sent out on loan soon but Jonathan Fortune (knee) and Therry Racon (foot) are still missing.
