Walsall boss Dean Smith believes the referee was right to deny Rotherham a second-half penalty during their 1-1 draw at home.
Rotherham striker Daniel Nardiello went down under a challenge from Walsall skipper Andy Butler in the 60th minute, but referee Stuart Atwell took no action.
Walsall boss Dean Smith insisted: "It was no penalty. I have seen it again. Nardiello kept going down and in the first half Paul Downing was booked when he (Nardiello) threw himself to the ground."
Rotherham, now unbeaten in eight league games, began the sharper side and took the lead when Kieran Agard's deep cross was headed back by Alex Revell for Nardiello to nod into the net for his fifth of the season.
But Walsall equalised in the 31st minute when a corner was only partially cleared and Sam Mantom hammered a volley from just outside the box which took a deflection on the way past keeper Scott Shearer.
In stoppage time Walsall substitute Craig Westcarr wasted a great chance to win it, driving high over from close range.
Saddlers' manager Smith felt the tough away game at Wolves on Tuesday, when they won 1-0, took something out of his men, which is why he made a couple of surprise changes.
"Sometimes you have to give credit to the opposition who came here with a game plan and tried to make it very difficult for us," he said.
"But we could have been better in the final third. We were superior in terms of possession, but you have to turn that into chances.
"We had a couple of players a bit below par but Rotherham are unbeaten and not an easy team to play against. You have to work hard.
"We had a couple of chances to win at the death but I was pleased with the way my players coped with the physical element in the game."
