It is the third match in a row that the Town have fielded the same starting XI, looking to build on the 4-0 home win over Peterborough and 1-0 victory at Southend.
Youth team striker Connor Tomlinson appears on the bench for the first time in a league match, with midfielder George Thorne absent after his girlfriend Beth gave birth to their first baby, a little girl who is yet to be named.
Congratulations to George and Beth from all 10,000-plus of us at Kenilworth Road tonight!
