Brentford's bid for Premier League promotion took a blow as their eight-match winning streak came to an end with a 1-0 loss at Stoke City.
The Bees entered the match knowing that they would leapfrog West Brom into second with a solitary point at the Potteries, but Lee Gregory capitalised on a poor save from David Raya to a Sam Clucas shot to tap home the only goal of the game shortly before the break.
Bryan Mbeumo could have given Brentford the lead shortly before they fell behind with a close-range header and Josh Dasilva stabbed an effort wide after good work from Ollie Watkins after half-time.
But Stoke dug in and despite being pinned in their own half for much of the second half, clung on to a lead which guarantees their place in the Championship next season, with Adam Davies making a fine save in second-half stoppage time to deny Ethan Pinnock.
Brentford go into the final game of the season, against Barnsley, hoping that their west London rivals QPR will do them a favour against West Brom on Wednesday. The result also confirms already-promoted Leeds' status as champions.
The clash against Barnsley, who could be relegated to League One this weekend, will be the last match at Griffin Park, should they be promoted automatically.
Fulham also have a chance of claiming automatic promotion after a 5-3 win over Sheffield Wednesday.
Aleksandar Mitrovic and Neeskens Kebano both scored twice for Fulham, who are two points behind West Brom with a game left to play.
Cardiff and Swansea both won to keep their play-off hopes alive.
Sixth-placed Cardiff beat Middlesbrough 3-1 to stay three points ahead of Swansea, who won 1-0 against Bristol City and have a one-goal inferior goal difference to their Welsh rivals.
Millwall are out of the running for a playoff place after a 4-3 loss at QPR left them in ninth, five points behind Cardiff.
Charlton scored a potentially crucial injury-time equaliser to draw 2-2 with Wigan.
The result leaves Charlton outside the relegation zone on goal difference while Wigan, who have a 12-point deduction for entering administration looming, are 10 points clear.
Luton are level on points with Charlton after a 1-0 win over Hull, who are three points from safety.
