keeper sending off

its my first game of the season and im playing stoke away,its coming up to half time and its 0-0,my keeper tim krul kicks the ball out of his hands up the field to which nile ranger flicks on and the ball reaches the oppisition keeper begovic,at this point of the keeper catching the ball his momentum when falling down means we are rewarded a free kick and he is sent off!!!!!!maybe i dont play often enough but this is the first time for me to see this,also in the same match we have a corner towards the end and nolan gets away a volley from inside of the box for it to only hit the post and deflect of the substitutes back and roll into the net!!!!!!i win 2-0 and a very fortunate win saying as my other goal was a pen with them also losing a man for the tackle:D
