Kightly suffered the setback during the home defeat against Liverpool last Tuesday and was ruled out of the weekend win at QPR. Wolves hope a two-week break from action after the derby will enable him to recover for the visit to face Newcastle.
Wolves boss Mick McCarthy said: "Kights is resting at the moment but the aim is to have him training again and available for the Newcastle game."
Defender Ronald Zubar has returned to training after suffering a knee ligament injury against Arsenal six weeks ago.
