Crawley boss John Gregory questioned the referee's time-keeping as they conceded deep into stoppage time in a 2-2 draw at Rotherham.
Visiting striker Matt Tubbs, who scored just once in 17 appearances for Rotherham earlier this season, opened the scoring against his former club after 23 minutes for his new club.
Rotherham equalized 10 minutes later from the penalty spot through Agard, but Josh Simpson shocked Rotherham by firing Crawley into the lead for a second time after 65 minutes and the visitors looked like having the last laugh.
But Agard rescued a point for Evans' promotion-chasers with his second of the game and his 15th of the season in the fifth minute of stoppage time, firing home after a sustained spell of home pressure.
Gregory was clearly disappointed his team could not hang on for a victory.
"We are devastated," he said. "It feels like a defeat conceding that goal so late in the game.
"Nevertheless there were a lot of good things, but when they scored five minutes and fifty seconds into added time so the referee is 50 seconds over the five minutes allocated and I don't know where he got that from.
"In the second half in particular we were outstanding and you won't see a better goal than our second anywhere in the world this weekend.
"The second 45 minutes was probably the best since I've been here.
"But it helps to play on a pitch like this. This stadium helps. It was a brilliant atmosphere, a great stadium to play in.
"We didn't play as well in the first half as the second.
"In the second half some of the stuff from us was brilliant. Defensively we dealt with everything they have thrown at us."
