WIGAN boss Gary Caldwell was dissatisfied with the performance of referee Lee Collins in the 0-0 draw with Millwall on Tuesday night.
Caldwell felt Collins was too severe in sending off Sam Morsy after the midfielder picked up two yellow cards when he fouled Jed Wallace and then Lee Gregory in the space of six first-half minutes.
There were few protests from his players at the decision, and Millwall went on to dominate the game, missing a number of clear-cut chances to take all three points.
Caldwell questioned whether Collins and his officials were influenced by the home support, claiming he also saw a foul by a Millwall player that warranted punishment.
"It was a little bit unfair but it was a good contest," the Wigan manager said. "I'm really proud of my ten players and the subs that came on that had to battle and scrap and fight and showed that every point is vital at this point of the season.
"It was a magnificent second-half performance."
"I think it was two clear fouls (by Morsy) but to get two bookings for both of them…I think the ref right from the very start was weak. When you come to a place like this you need the ref to be strong. The crowd are obviously on his back, the technical area is on his back and every decision went their way.
"I saw a two-footed challenge right in front of the linesman and the fourth officials and nothing gets done.
"I'm disappointed with that but proud of my players."
