Aston Villa edged closer to Barclays Premier League survival after collecting a hard-earned point against West Brom at the Hawthorns.
But it needed a controversial refereeing decision by Mark Clattenburg to deny Albion victory after Villa defender Alan Hutton clearly used his arm to block a goal-bound header from Liam Ridgewell.
But Clattenburg and his assistant failed to spot the incident and the visitors survived to earn their 16th draw of the campaign.
Alex McLeish's side deserved their share of the spoils on the balance of play and were again left to rue failing to be more clinical in front of goal
Gabriel Agbonlahor, Chris Herd and Charles N'Zogbia all failed to make the most of gilt edged chances and Albion's Ben Foster was the busier of the two keepers.
The return of experienced defender Richard Dunne after a two and a half month lay-off with a broken collarbone also brought a steadying presence to the Villa back four.
Villa looked full of attacking intent in the early stages and Charles N'Zogbia found Stephen Warnock in space and his shot was blocked by Billy Jones.
But Albion nearly caught out Villa during their first serious counter-attack.
Carlos Cuellar failed to make clean contact on his attempted clearance from Shane Long's cross-shot after a determined run by the Republic of Ireland striker. The loose ball broke to 11-goal leading scorer Peter Odemwingie whose close-range back heel was blocked.
The first clearcut chance fell to Villa midfielder Chris Herd after 26 minutes.
Dunne showed good control to the right of Ben Foster's goal before sending over a low cross which landed in Herd's path. He struck his shot firmly enough but it flew straight at Foster who was able to make the save.
