Wilkinson injured himself initially in the defeat by Gloucester in September
Newcastle Falcons have re-registered fly-half Jonny Wilkinson and lock Geoff Parling for the latter stages of the European Challenge Cup.
The duo have recovered from injury and boss Steve Bates has restored them for the 12 April quarter-final at Saracens.
Parling has agreed to join Leicester at the end of the season, while Wilkinson, who could return at Wasps on Sunday, has been linked with a move to France.
Meanwhile flanker Will Welch has signed a new one-year deal with the club.
The Newcastle University history student made his first-team debut against Newport Gwent Dragons.
