Timbers comeback to draw with Dallas
Scott Sealy scored for Dallas (5-11-8) off a cross from Brek Shea in the 51st minute of the matchup between the bottom two teams in the Western Conference.
Jewsbury's volley was a left-footed blast from the top of the penalty box after a corner kick ricocheted out to him. Until that point it appeared Portland would go down to another scoreless defeat after being shut out in its previous three games.
The Timbers (5-12-5) outshot Dallas 19-8, and maintained their aggressiveness down the stretch with temperatures in the mid-90s.
The game marked the return of Shea, the star midfielder who had been benched for two straight games and hadn't played since being taken out of a July 18 game against San Jose.
Dallas dominated Portland 5-0 in their last meeting, on July 21 and Timbers general manager and interim coach Gavin Wilkinson accused his team of quitting.
Portland typically plays well at raucous Jeld-Wen Field, where all of its wins have come this season, and Dallas entered the match having won only one of 10 on the road.
Neither team had an exceptional start after the scoreless first half, where possession time was essentially even, though Portland outshot Dallas 9-4 before the break.
FC Dallas midfielder James Marcelin was making his return after being waived by Portland.
