In a scrappy, physical game, Stags had soaked up all the home side had to offer and led through a Lucas Akins penalty as the game went past the six added minutes that had been indicated.
But then a series of refereeing decisions went against them as Ryan Sweeney was ordered off after a bang to the head, Stevenage grabbed an equaliser from a drop ball the visitors felt they should not have been given and Louis Reed was red-carded for his protests in a fiery finish to the contest.

Solid display at left back and caused problems going forward with his cutting passes. Photo: Chris Holloway
6. LOUIS REED 7
Tried to get his side going in a scrappy clash. Lost his temper with the referee at the end and took a costly and needless red card. Photo: Chris Holloway
7. JON RUSSELL 7
Another good full debut at the end of a tiring week in which a return to playing action was coupled with a new born baby. Withdrawn after 58 minutes. Photo: Chris Holloway
8. WILL EVANS 7
Ran his heart out but not much came off. Fine pass to set Irow free down the left. Was involved in winning the penalty with his hard work holding off a defender to chest the ball to Oates in the box. Came off for Victor Adeboyejo on 83 minutes. Photo: Chris Holloway
