has pulled out of performing in her West End play for the second night in a row due to health concerns.
The Funny Girl actress, who stars as Fanny Brice, will be replaced by her understudy for Tuesday's show.
A tweet from the Savoy Theatre said:
Due to the indisposition of Sheridan Smith the role of Fanny Brice will be played by Natasha J Barnes at tonight's performance of Funny Girl

Sheridan has used Twitter to hit out at critics in the wake of Sunday evening's Bafta TV awards and has not appeared on stage since.
She wrote: "When will u stop bullying? I had the best night in memory of my girl @LisaLynch."
Sheridan was nominated for best leading actress for her role in The C Word as the late Lisa Lynch, but lost out to Suranne Jones.
Bafta host Graham Norton's opening monologue appeared to contain a joke at Sheridan's expense, when he quipped: "We're all excited for a couple of drinks tonight. Or, as it's known in theatrical circles, a few glasses of 'technical difficulties'."
This came less than two weeks after a performance was cancelled halfway through, which producers said was down to "technical difficulties".
Sheridan had earlier denied speculative reports in the press that the performance of Funny Girl had to be stopped early because she had been drinking.
A spokesman for the actress has said that the allegations are "categorically not true".
Sheridan also responded on Twitter to a story alleging that she had been a sore loser at the Baftas, writing: "Why watch me & not the show????? Weird."

Apparently referring to the fact that she has felt unable to perform, Sheridan then tweeted: "Well done press! U let down me, the cast & everyone who spent money to see me.
"I apologise Profusely! Sorry! Sorry I'm not strong enough."
She added: "I love you who have my back, beyond belief. Sorry x"
