Stevenage top scorer Chris Holroyd could return after being ineligible for the 2-0 FA Cup win over AFC Wimbledon.Injury-prone striker Ben May could return after being rested for the cup game but Lee Boylan (calf) and Darren Murphy (ankle) remain absent.
Northampton manager Ian Sampson is set to name an unchanged side.
Captain Andy Holt came off at half-time in the 2-0 win over Stockport but should be fit, while striker Tadhg Purcell (knee) is their only absentee.
Northampton Town manager Ian Sampson tells BBC Look East: "Graham Westley had a successful career as a manager, it's his first year in the league and I've been very impressed with what they do.
"We're looking to keep Kevin Thornton in the team, and based on what he showed against Stockport, he deserves another chance.
"I wouldn't class it as a derby for Northampton, even though it's only 50 miles away."
