The hosts took the lead with a Martin Petrov penalty, before a Billy Jones own goal looked to have secured victory for the Reebok Stadium outfit.
However, Roy Hodgson’s men fought back and goals from Chris Brunt and a last-minute James Morrison equaliser meant the points were shared.
The result leaves the Trotters still in the dropzone, and Owen Coyle was not happy to have thrown away the advantage in the game.
“It’s a horrible feeling, no doubt about it, taking a point from a game that should have been all three,” he told Sky Sports.
“I’m disappointed, absolutely. I think we did enough to earn the three points in the game.
“We got ourselves in a terrific position. A lot of good play.
“Ben Foster was outstanding in goal for West Brom today and you can understand the clamour for him to get involved in the England set-up again. But for our part we should have seen the game through 2-0,” he concluded.
Bolton have to play Stoke at the Britannia Stadium on the last day, and must win to have any chance of avoiding the drop.
