Peterborough United scored two late equalisers to earn an FA Cup fourth-round replay at London Road after dramatically drawing 2-2 at West Brom on Saturday.
Saido Berahino shrugged off speculation about his future by giving West Brom the lead with a brilliant strike after just 14 minutes at The Hawthorns, beating Jak Alnwick with a clipped shot from outside the penalty area.
The Premier League outfit had only won one of their last five matches in all competitions and Peterborough deservedly equalised through Shaquile Coulthirst with 11 minutes to go after some slack defending.
Berahino put West Brom back in the lead with another fine strike on 84 minutes but substitute Jon Taylor hit back with a volley a minute later to set up a replay.
Tony Pulis handed a rare start to striker Berahino, who had a short loan spell at Peterborough in 2012, with Jonny Evans acting as captain due to Darren Fletcher's knee injury.
James McClean created an opening for Lambert in the first minute, but the striker's first touch let him down.
West Brom took the lead after 14 minutes, with Berahino on target. The striker had scored six goals and supplied four assists in his previous five FA Cup matches and added to that impressive record with a fine finish from Lambert's pass after Craig Gardner had smartly won the ball in midfield.
Lambert had a glorious chance to double the lead two minutes into the second term, but he scooped his shot into Alnwick's arms from close range after Stephane Sessegnon opened the visitors up.
Gardner could have secured the result for West Brom but he shot well off target on 70 minutes after Berahino had combined with Salomon Rondon.
Peterborough equalised within a minute, Taylor sensationally volleying home from Santos' pass to earn his team a replay at London Road.
