Gad earned a Tony Award nomination for originating the role of Elder Cunningham, the earnest but inept Mormon missionary in the Tony Award-winning hit musical authored by "South Park" creators Trey Parker and Matt Stone, and Avenue Q Tony winner Robert Lopez.

Gad sustained an injury during the Oct. 27 performance of The Book of Mormon and was replaced by his understudy, Jared Gertner (Broadway's Spelling Bee and Off-Broadway's Ordinary Days), for the second act of the performance. Gertner has gone on in Gad's place throughout the weekend.

Representatives for The Book of Mormon confirmed to Playbill.com that Gad will return to the production Nov. 1. The actor also shared the news via Twitter: "Thank u all for your support. Back in the saddle tonight."

NBC recently picked up a TV pilot for a comedy series that Gad is developing. Gad also appeared in Broadway's The 25th Annual Putnam County Spelling Bee, and was a correspondent on "The Daily Show With Jon Stewart." His TV credits also include the series "Back to You" and appearances on "Bored to Death," "Californication," "Numbers" and "Party Down." He was the subject of Playbill.com's Leading Men column in June. 

The Book of Mormon also features Tony Award nominee Andrew Rannells (Jersey Boys) as Elder Price, Tony Award winner Nikki M. James (All Shook Up) as Nabalungi, Tony Award nominee Rory O'Malley (The 25th Annual Putnam County Spelling Bee) as Elder McKinley, Michael Potts (Grey Gardens) as Mafala Hatimbi, as well as Lewis Cleale, Scott Barnhardt, Justin Bohon, Darlesia Cearcy, Kevin Duda, Asmeret Ghebremichael, Brian Tyree Henry, Clark Johnsen, John Eric Parker, Jason Michael Snow, Benjamin Schrader, Michael James Scott, Brian Sears, Lawrence Stallings, Rema Webb, Maia Nkenge Wilson, Tommar Wilson, Graham Bowen, Ta’Rea Campbell, Tyson Jennette and Nick Spangler.
