The Portland Timbers were held to a goalless draw by FC Dallas on Sunday, having already clinched an MLS Cup playoff berth by virtue of results elsewhere.
Austin FC's 2-1 defeat to the LA Galaxy on Saturday, which led to the team firing head coach Josh Wolff, ensured they could not overhaul Portland for the Western Conference's final wild-card spot.
The Timbers still went with a strong lineup for their final home game of the regular season but had to settle for a point.
Both Portland and Dallas had their chances, having 19 and 18 shots respectively, with the hosts almost finding a winner in second-half stoppage time as Dario Zuparic's header was cleared off the line.
Perhaps their best opportunity came in the 88th minute, but Dallas goalkeeper Jimmy Maurer pushed Felipe Mora's attempt over the crossbar to preserve the visitors' clean sheet.
Dallas, who had already been eliminated from the playoff race, sit 11th in the West, while Portland missed a chance to close the gap to the automatic qualification spots, which are now out of reach due to seventh-placed Minnesota United boasting two more wins with one game remaining.
Data Debrief: Timbers end playoff exile
Portland enter the MLS Cup Playoffs for the first time since 2021, having missed out in both of the last two campaigns.
They finished as runners-up when they last made the postseason, while three of their last six playoff appearances have seen them make the MLS Cup Final.
