New York City FC's joy in taking the lead in the MLS Cup final was tempered by an ugly incident as Jesus Medina was hit by a missile during celebrations.
The club went ahead 1-0 against Portland Timbers when Valentin Castellanos nodded them into the lead in the first half.
But even as the Argentine celebrated, his team-mate fell to the floor after being struck in the chest by a beer can.

The bigger picture
NYCFC went on to record their first-ever MLS Cup victory in their sixth season as a franchise.
The closest the club has previously come was the quarter-final stage, while in 2020 it failed to progress past the first round of the play-offs.
Timbers forward Felipe Mora frustrated their victory celebrations with an equaliser deep into injury time but NYCFC recovered to take the title on penalties, coming out on top by a 4-2 margin in the shoot-out.
Castellano, who first joined NYCFC from fellow City Group outfit Torque in 2018, proved key to their progress across the season.
The Argentine took his MLS tally in 2021 (including play-offs) to 22 with this latest strike and takes the league's top scorer title.
