West Bromwich Albion have announced that they have dismissed Tony Pulis from his role as head coach of the club.
The 59-year-old has left his position at The Hawthorns after just two wins in his last 21 Premier League games following Saturday's 4-0 defeat to Chelsea.
West Brom are just a point and a place above the relegation zone after an 11-game winless run in all competitions.
Baggies assistant head coach Gary Megson -- a former manager of the club between 2000 and 2004 -- will take charge of first-team affairs until further notice.
A club statement read: "West Bromwich Albion have today terminated the contract of head coach Tony Pulis."
West Brom chairman John Williams added: "These decisions are never taken lightly but always in the interests of the club. We are in a results business and over the back end of last season and this season to date, ours have been very disappointing.
"We would like to place on record our appreciation of Tony's contribution and hard work during a period of transition for the club which included a change of ownership. We wish him well in his future endeavours."

In a statement released by the League Managers Association, Pulis highlighted his accomplishments and the stability he brought to the club during an ownership change.
It read: "Over the last three seasons we have achieved a great deal and I am proud to have managed West Bromwich Albion.
"I would like to thank the two owners, Jeremy Peace and Mr Lai, the Board and fans for their support during my time at West Brom. Jeremy Peace and Mr Lai have played an important role in the off-field success and given the team a platform to build from. My remit was to develop the squad and ensure we delivered results which would in turn improve the club's financial position. We have achieved this year on year and I am pleased to have played a part in the club's growth.
"Our final league position in the last three seasons has represented the accomplishment of our targets as a club; sustaining our status in the Premier League and delivering stability, throughout the club's transition of ownership.
"We enjoyed a fantastic season last year, finishing 10th in the Premier League for only the third occasion in Albion's history and finished as the top midlands team for only the second time since 1967-68. I strongly believe that this group of players can return to this level of performance and finish in the upper reaches of the Premier League.
"This season, expectations have risen and although we are disappointed with some of our results, one thing I would never question is this group's work ethic and application. The players and backroom staff are extremely hard working professionals and I would like to thank them for their efforts and wish them the very best in the future."
West Brom owner Guochuan Lai watched the Chelsea defeat after flying over from China for a pre-arranged trip and is now tasked with finding a new manager, with Aberdeen boss Derek McInnes linked to the post.
Pulis replaced Alan Irvine when the Baggies were a point above the relegation zone in January 2015, eventually leading them to 13th.
They finished 14th in 2015-16 and came 10th last season but failed to win any of their final nine matches.
Pulis made a defence of his record before the Chelsea loss, suggesting West Brom would struggle to get a better replacement.
"If I left tomorrow I'd put my record on the table and put it in front of anybody and see what they think of what I've done here in three years,'' he said on Friday.
Northern Ireland boss Michael O'Neill is interested in the West Brom job and is on the club's list of potential options, sources have told ESPN FC.
