Jay Rodriguez scored an 89th-minute penalty at the Hawthorns to earn West Brom a 2-2 Championship draw with Martin O'Neill's Nottingham Forest, who had twice led.
A Stefan Johansen own goal gave Forest the half time lead, only for Jacob Murphy to equalise at the start of the second half.
Ryan Yates restored Forest's advantage in the 65th minute but they were denied victory when Alexander Milosevic fouled Dwight Gayle, allowing Rodriguez to net from the penalty spot for his 17th goal of the season.
Forest, now under the watchful eye of O'Neill and his assistant Roy Keane, remain ninth in the table.
Famara Diedhiou's injury-time penalty maintained Bristol City's winning run as they came from behind to beat QPR 2-1.

It was a ninth straight win for City in all competitions, with their seventh in the league moving them up to fifth in the table.
