The midfielder was substituted just before half-time during the league defeat at Port Vale on Monday with a calf problem.
Webster has been troubled by the injury since mid-December and was not risked from the start against Shrewsbury on New Year`s Day.
He returned to the starting line-up against Vale but boss Paul Peschisolido will need to be convinced of Webster`s fitness before deciding on his side for the third round tie.
Defender Scott Malone is available after extending his loan spell from Wolves until the end of the season.
Paul Boertien, Jimmy Phillips, Bryan Hughes, Greg Pearson and Shaun Harrad are options for Peschisolido should he wish to make changes.
