Seattle Sounders denied Portland Timbers victory with an injury-time equaliser in Thursday's 1-1 draw in MLS.

The Timbers looked set to claim maximum points thanks to Andres Flores' 10th-minute opener at CenturyLink Field in Seattle.

Seattle's three earliest goals conceded this season have all been scored by Portland, according to Opta.

But reigning MLS champions the Sounders salvaged a last-gasp draw courtesy of Will Bruin's leveller in the third minute of stoppage time.

It meant Portland have conceded 12 goals in the final 15 minutes of matches this season, three more than any other MLS club, per Opta.

The result ensured the top of the Western Conference standings remains unchanged, with the Sounders ahead of the Timbers on goal difference.
