Jaroslaw Niezgoda opened the scoring eight minutes into the second half only to see former Portland man Aaron Long level in the 67th minute.
Story of the match
The ninth minute provided the Red Bulls with the game's first opportunity. After a foul by Pablo Bonilla, an in-swinging cross met the head of Dylan Nealis, but he couldn't direct his effort on target.
Five minutes later, Frankie Amaya was next to try his luck, taking on several Portland defenders, his shot going just wide.
Yimmi Chara and Santiago Moreno had some neat interplay that led to the latter sending a wonderfully chipped pass that Chara sent well over from inside the six-yard box.
On the counterattack, Niezgoda fed Moreno and after switching the ball onto his right foot, the Colombian let fly from outside the box that hit the crossbar.
Five minutes from halftime, Chara was again played in via a chipped effort from Marvin Loria, but he again made a mess of the chance, slicing his shot wide.
David Bingham was soon called into action as the Timbers goalkeeper did well to get a hand to a Tom Barlow shot, Bonilla clearing away any further danger.
In the 48th minute, the visitors nearly opened the scoring. Loria sent in a dangerous low cross from the left fell to Niezgoda on the opposite side of the pitch.
The Pole crossed the ball back and eventually, Justin Rasmussen drove a right-footed strike at goal that was deflected behind for a corner.
Portland then opened the scoring in the 53rd minute. Loria found Moreno on the right wing and his low cross was fed into the path of Niezgoda, who scored with his left foot.
From a set-piece, the Red Bulls equalized. An in-swinging corner was headed back across the box and Long finished past Bingham to make it 1-1.
Six minutes ftom time, Bingham awkwardly handled a Lewis Morgan shot, but adjusted in time to preserve the tie and eventually earn his side a point.
Man of the match: Santiago Moreno
Had he been a bit more accurate, he would have grabbed a goal. Still, his assist helped end the Timbers' 335-minute scoring drought and he was their most impactful player on the night.
