After a goalless first half, the game sprang into life when Grant Hanley received his marching orders for an alleged foul on Steve Morison in the area.
Shaun Williams converted from the spot but Rovers hit back, Michael Keane notching his first goal for the club with a back post header.
But with just two minutes left on the clock Keane was then adjudged to have committed an offense in the box himself, Simeon Jackson, the fouled player, making no mistake from 12 yards once more.
However Rovers are made of much sterner stuff thesedays and in the second of five added minutes, Joshua King poked the ball home for a deserved point.
"Everything that we demanded and expected of the players has really come to the fore today," said Bowyer after the game.
"With the events that have happened you are pleased coming away with a point, but the major talking point is obviously the first penalty.
"The lad has his arm round Grant's neck, and then to send him off just compounds the decision even further because Matt Kilgallon is round clearing the ball.
"But the reaction and the response was phenomenal. After that you are talking about nothing but positives because of the character and the spirit.
"We spoke about it on Tuesday night and to do it again is a measure of how far we have come and how we have to go again.
"It was a tremendous effort from everyone, you saw them at the end, they were on their knees."
