Last Defender vs Through Ball

It's 1-1 in the 78th minute. A long through ball is played over the top for the opposition striker, who is quicker than you. You are the last defender and manage to get goal-side but only just — you are running shoulder to shoulder with him into your own third, angling him towards the touchline. The goalkeeper is off his line at the edge of the box. A rash tackle risks a red card and a penalty or free kick.
