West Brom have sacked Eric Ramsay just 44 days after appointing him as head coach.
Ramsay replaced Ryan Mason in January after moving from MLS side Minnesota United, but struggled during his time at The Hawthorns, failing to win any of his eight league games in charge.
The 34-year-old drew four and lost four of his Championship matches during his short stint.
His Baggies side were also knocked out of the FA Cup after they lost at Norwich.
A statement released after Tuesday night's 1-1 draw with Charlton said: "West Bromwich Albion have parted company with men's first-team head coach Eric Ramsay.
"Assistant head coach Dennis Lawrence has also departed The Hawthorns.
"The club would like to place on record its thanks to Eric and Dennis and wishes them well for the future.
"First-team coach James Morrison will oversee first-team affairs on an interim basis."
West Brom sit 21st in the Championship, one point above the relegation zone.
Eric Ramsay speaking after West Brom's 1-1 draw with Charlton:
"We're not talking about this performance in isolation - we are adding this to multiple draws, not enough wins and not enough getting over the line so it has the feeling of a step backwards.
"I know what this situation needs at the moment - it needs wins, it doesn't need draws.
"The number of chances were enough to win the game but it wasn't good enough.
"We are lacking a real spark and quality in front of goal.
"I am not sat here on the back of five losses where the team has not been competitive.
"Over the last four league games, the team has been competitive, it's fighting and I don't feel there's a lack of connection between me and the team."

Simply put, they replaced a project with a project at the wrong time.
Having parted company with Ryan Mason, a 34-year-old in his first senior role in management, the club then opted for a man a few months younger in Eric Ramsay.
He certainly had some more experience in a senior role, having spent two years at Minnesota United in MLS, but inexperience still shone through from day one.
An ill-fated attempt to switch to a back three mid-season resulted in an opening defeat to Middlesbrough and then the biggest second-tier home defeat in the club's entire history - as they were crushed 5-0 at home by West Brom.
The system was tweaked and four draws followed in their next six league games, but the damage had already been done. Just 44 days, nine games (including one in the FA Cup) and zero wins.
Having met and interviewed Ramsay myself I can vouch for the fact he's a very impressive individual and an excellent speaker. He is also a talented coach with a backlog of work at Chelsea and Man Utd before his time in the USA.
But he was thrown in at the deep end at The Hawthorns, and the club clearly couldn't risk any longer without a win. Particularly when you consider their next game is a trip to Oxford United on Saturday, who currently sit two places below them in 23rd.
February 28: Oxford (A)
March 7: Sheffield United (A)
March 11: Southampton (H)
March 14: Hull (H)
March 21: Bristol City (A)
