Albion came from two goals behind to earn a 2-2 draw at Huddersfield Town on Saturday afternoon.
Jed Wallace’s brace cancelled out early efforts by Terriers midfielder Tino Anjorin to secure a share of the spoils in Yorkshire.
Steve Bruce’s team return to action with a trip to Wigan Athletic on Tuesday night.
Steve Bruce named an unchanged XI from last weekend’s 5-2 win against Hull City.
But his men were a goal down inside 11 minutes, Anjorin curling home from the edge of the box following a clever corner routine.
And Huddersfield doubled their lead on the half-hour mark. Anjorin, perhaps controversially, pickpocketed O’Shea before running through and finishing past David Button.
Yet the visitors dusted themselves down and pulled one back before the break – Grady Diangana beating his man and crossing for Wallace to convert his first since joining in the summer.
Within 12 minutes of the restart they were then level, and it was Wallace again. A good cross from Jayson Molumby was flicked on by John Swift, and Albion’s right-winger was on hand to send a volley into the top corner.
The Baggies were now in full flow and searching for a third – Karlan Grant seeing a fierce shot saved and the impressive Diangana smashing narrowly wide.
Yokuslu nodded Darnell Furlong’s brilliant ball off-target as the clock ticked closer to full-time, and Huddersfield might have stolen it when substitute Jordan Rhodes headed narrowly wide.
Three minutes from the end Albion had a very strong penalty shout turned down, despite Grant appearing to have been fouled inside the area, though the hosts also hit the post via Josh Ruffels’ effort.
Five minutes of stoppage time brought one final push – however the points were shared from an entertaining game at the John Smith’s Stadium.
Albion: Button; Furlong, Ajayi, O’Shea, Townsend; Molumby (Robinson 82), Yokuslu; Wallace, Swift, Diangana; Grant.
Substitutes: Palmer, Bartley, Gardner-Hickman, Reach, Livermore, Fellows.
