Representatives were initially hopeful that the leading man would be well enough to return to On the Twentieth Century mid-week.
"Peter Gallagher continues to recover from a severe sinus infection. He will be out of On the Twentieth Century tonight through the weekend, returning on Tuesday, March 3," representatives told Playbill.com Feb. 27.
Gallagher fell ill just prior to the Feb. 21 Saturday evening performance, prompting a last-minute cancellation of the performance. His understudy, actor James Moye, stepped into the role this past week and will continue with co-star Kristin Chenoweth in the romantic comedy until Gallagher's return.

The musical began performances Feb. 13 at the American Airlines Theatre. On the Twentieth Century will officially open March 12 for a limited 20-week engagement through July 5 at the American Airlines Theatre.
The musical — featuring music by Cy Coleman and book and lyrics by Betty Comden and Adolph Green — premiered on Broadway in 1978 under the direction of Harold Prince and won Tony Awards for Best Original Score and Best Book of a Musical. Here's how Roundabout bills the classic: "It's nonstop laughs aboard the Twentieth Century, a luxury coach travelling from Chicago to New York City. Luck, love and mischief collide when the bankrupt theater producer Oscar Jaffe (Gallagher) embarks on a madcap mission to cajole glamorous Hollywood starlet Lily Garland (Chenoweth) into playing the lead in his new, non-existent epic drama. But is the train ride long enough to reignite the spark between these former lovers, create a play from scratch, and find the money to get it all the way to Broadway?"
The American Airlines Theatre on Broadway is located at 227 West 42nd Street. For tickets, call (212) 719-1300 or visit RoundaboutTheatre.org.
