I just heard some loud celebratory-type sounds emanating from the football ground as I was having a wander round with the dog. My interpretation was that Southend had been awarded, and had scored from, a penalty (big shout, a hush and then a very big shout) but this has not been confirmed by my electronic devices. The score remains at Southend 2 - 2 Scunthorpe, which seems have been the case for most of the second half.
Edit: a very late goal (90" +2") does indeed seem to have won the game for The Bleeders but it doesn't seem to have been a penalty.
Another edit: that is a very good win for Saarfend, who have lost their previous 4 matches. Scunthorpe are 4th in the division, compared to Southend's 20th at the start of the game. Scunthorpe's season appears to be coming unravelled somewhat as their last win was 5 games ago.
