Earlier this week Hereford United manager Martin Foyle watched tomorrow's opponents Lincoln City in their FA Cup replay against Walsall which the Imps won.
"They are on a super run of nine games," Foyle told BBC Hereford and Worcester.
"I saw them at Walsall during the week.
"They've certainly improved no-end.
"We know this is going to be a tough game, probably very similar to the Wrexham game.
"If we are on our game, then it's game on.
"But if we're off the pedal, then we'll struggle."
Andy Gallinagh is expected to return to the starting eleven after missing the Wrexham game with an illness.
And Luke Graham will partner Stefan Stam in the heart of defence as Chris Todd has been recalled by Forest Green Rovers.
