Commons is getting closer to Rams return
Commons' injury-hit season has seen him make only five starts and the Scottish international forward has missed the last five matches.
He has been working his way back to fitness but is now troubled by tight calf muscles.
"Kris Commons broke down last week with sore calves when he was doing one-on-one work with Johnny Metgod. He might train at the end of the week," said manager Nigel Clough.
Derby have pencilled Commons in for the reserve-team game against West Bromwich Albion at Alfreton Town's Impact Arena next Wednesday afternoon.
Clough also hopes to involve Chris Porter, Steve Davies and Jake Buxton.
"We could have a hell of a reserve side out there," said Clough.
Porter warmed up with the first team before Saturday's home victory over Reading.
The striker, Clough's first signing as Rams manager, has not played in a competitive match since March because of a hip injury that required surgery.
An ankle problem has kept Davies out since the home win against Plymouth Argyle at the end of August.
"Steve Davies had a good week at Lilleshall and, hopefully, he will join in training at the end of the week," said Clough.
"We've got him pencilled in for the Reserve game, Jake Buxton as well."
Buxton started the first six games before he underwent a hernia operation and then picked up a groin injury.
Giles Barnes is still recovering from a ruptured Achilles' tendon.
The 21-year-old attacking midfielder had surgery in August after being injured in the final pre-season friendly against Stoke City.
"Giles is probably the furthest away of the injured players," said Clough.
"It will probably be a couple of weeks before he is doing intensive ball work."
Barnes has been plagued by serious injuries since the Championship play-off final in May 2007. He has also had a broken foot and a knee injury.
He has made only 29 senior appearances in the past two and a half years and had a loan spell at Fulham last season but did not make their first team.
His contract is up in the summer.
FORMER Rams reserve-team striker Paris Simmons has joined Polish club WKS Slask Wroclaw on a week's trial.
The 19-year-old, who made one senior appearance for the Rams, was released at the end of last season.
