Albion chairman John Williams and Chief Executive Martin Goodman have been dramatically sacked as a result of the club's disasterous season.
The Baggies are now seven points from safety with only 11 games left to play, following last night's 3-0 defeat at Chelsea.
Club owner Guochuan Lai, who appointed by Williams and Goodman, has now turned to former CEO Mark Jenkins to try and salvage Albion's season.
"We would like to thank John and Martin for all their efforts since their appointments and wish them well for the future," said an official statement.
Albion are rock bottom of the Premier League having lost the last three games and have only 20 points from 27 fixtures this term.
After two victories at the start of the season in the league, the club then went a record 21 games in all competitions with another victory.
Former Blackburn chairman Williams was criticised after waiting until mid-November to axe former Head Coach Tony Pulis.
The decision to appoint Alan Pardew, based largely on his previous experience managing in the Premier League, also raised eyebrows.
"There is much to do but for now the focus must solely be on the remaining games of this season," said the returning Jenkins.
