This week's edition of Instant Replay looks at the following five plays:
1. Birahim Diop's opening goal in KC-NE, which the Revolution claimed was offside;
2. Eddie Gaven's disputed penalty kick which opened the scoring in CLB-COL;
3. Jason Garey's goal which was called back due to a very close offside in CLB-COL;
4. An alleged foul on Kyle Nakazawa which led to DC United's second goal in DC-PHI;
5. Brian Ching's opening goal in HOU-CHI which saw GK Sean Johnson fall hard to the ground.
