HARRISON, N.J. (AP) - Vicente Sanchez scored on a penalty kick in the 72nd minute after a controversial decision by the substitute referee and the Colorado Rapids and new coach Pablo Mastroeni opened the season with a 1-1 tie with the New York Red Bulls on Saturday.
Thierry Henry scored on a header in the 57th minute for the Red Bulls, the defending Supporters' Shield trophy winners who were trying to bounce back from a dismal season-opening performance in 4-1 loss at Vancouver last weekend.
The Professional Referee Organization, which manages on-field officials for Major League Soccer, has locked out officials from the Professional Soccer Referees Association, because the two sides have failed to reach agreement on a contract after the officials formed a union last year.
Substitute referee Alan Kelly awarded the penalty kick after defender Jamison Olave used his chest to knock Marvin Chavez to the grass as he took a pass from Sanchez.
The crowd of 20,542 booed after the call and Olave seemed shocked.
Sanchez deposited the kick from the spot into the right corner of the net. Red Bulls keeper Luis Robles did not have a chance to stop it.
