Defender Glad To Be Back Available"It feels good to be back,” said Knight-Percival.
"It is great to be back and be available for selection for the game.
"You can ask any player, you don’t want to be watching games, it’s frustrating.
"You always want to be able to help out and sort of pitch in a bit, any way you can."
And the defender is glad to be playing again after being stuck on the sidelines for the past few games after receiving a red card in the Port Vale game.
"It gives you confidence but they’re going to be a changed team now," he said.
"We are a changed team now so you don’t know what is going to happen."
But Knight-Percival, who did not feature in that match, believes both sides have changed since then.
Town impressively beat the Blades 4-2 in the reverse fixture at Bramall Lane in November.
"All the games at this time of the season are massive games so it is going to be another big test,” said the Town captain.
And Knight-Percival, who returns from a three-match suspension, admits games at this time of the season are huge.
Town take on the Blades in the Sky Bet League 1 clash at Greenhous Meadow on Tuesday night (7.45pm kick-off) looking to get back to winning ways.
Defender Nathanial Knight-Percival believes Sheffield United will provide another big test for Shrewsbury Town but is confident heading into the clash.
