this is my take on the two possible penalties:
On 57 minutes, Potter got into the area on the right, and went down. It was a bit too far away for me to see if it should be a penalty, but John Peers texting into our commentary on iFollow Stags from behind the goal and with a good view, thought it should have been. From the pitchside video, Jacobson sticks out a leg as Potter cuts inside him, Potter goes down, Jacobson withdraws his leg and protests his innocence. I think that was a penalty, though it is a very hard one to tell, and the referee probably couldn’t tell. The referee did not book Potter for diving.
On 90+1 minutes, Olejnik had to stretch to tip a dangerous cross from Nick Freeman over the bar. From the resulting corner, Wycombe claimed for a penalty which was not given. From the video, Mackail-Smith lofted a shot towards the roof of the net from 4 yards. Angol, who was about a yard away, blocked the ball with his right arm, with his elbow sticking slightly out from by his side. From the video, you can see that the referee had a perfect view and carried on. It was a difficult one for the referee (as was the Potter possible penalty earlier). It could have been given, and I would say the two incidents evened themselves out.
