Karlan Grant scored his first goal for West Brom to rescue a point and deny a frustrated Brighton their first home win of the season.
In only his second game since joining from Huddersfield Town less than two weeks ago, Grant collected a low cross from Callum Robinson and crafted space before firing home an equaliser with seven minutes remaining.
The finish cancelled out Jake Livermore's first-half own goal, which arrived when Branislav Ivanovic desperately slammed the ball in off his team-mate with Brighton's Neil Maupay lurking.
Brighton restricted West Brom to shots from range but after Matheus Pereira had twice gone close for the away side, Grant powered home from 12 yards.
