West Brom's latest stay in the Premier League could officially end tonight when they go to Arsenal.
The Baggies have secured two draws in their last two games against local rivals Aston Villa and Wolves, leaving them 10 points from safety with four games to play.
Defeat in North London will confirm relegation back to the Championship on Sunday night, but even a win or a draw may not be good enough - though demotion wouldn't be known until Monday evening when Fulham and Burnley play.
When Mikel Arteta's side visited The Hawthorns in January they ran out 4-0 winners, but the Gunners will be going into Sunday's match off the back of their limp Europa League semi-final defeat to Villarreal.
What time is Arsenal vs West Brom?
Kick-off at the Emirates is at 7pm on Sunday.
Relegation rivals Fulham and Burnley take each other on at Craven Cottage on Monday night.
Arsenal vs West Brom TV channel

Coverage begins at 6.30pm on BT Sport 1.
Robert Snodgrass (back) looks set to miss the rest of the season, while loanee Ainsley Maitland-Niles will miss the clash with Arsenal as he is ineligible to face his parent club. Otherwise Allardyce may stick with the same team that draw 1-1 with Wolves on Monday night.
West Brom's next game will be on Sunday, May 16, when Liverpool visit The Hawthorns.
Kick-off will be at 4.30pm.
