NBC has solidified its spring scheduling plans, setting premiere dates for three new series and the return of comedy “The Carmichael Show.”

“Carmichael,” which showed some ratings promise when it aired briefly last summer, will be paired with new comedy “Crowded” (from the exec producers of “Hot in Cleveland”) as part of a new comedy hour on Sundays at 9 starting March 13. “Carmichael” will come aboard that night with a pair of episodes, and “Crowded” has its debut on March 20. Both shows will follow the new series “Little Big Shots,” hosted by Steve Harvey, which premieres March 13.

Both comedies will get special preview episodes following episodes of “The Voice,” which returns to the network’s lineup in at the end of February. The “Carmichael” preview is on tap for Tuesday, March 8 at 10:30 p.m., and “Crowded” will get an hourlong preview on Tuesday, March 15.

NBC will also call on “The Voice” to provide sampling for new medical drama “Heartbeat.” The character-driven series, which follows the professional and personal life of renowned heart transplant surgeon Dr. Alex Panttiere (Melissa George), will preview Tuesday, March 22 at 9 p.m. and then bow in its regular timeslot the following night at 8. “The Mysteries of Laura,” currently airing Wednesdays at 8, will have wrapped its 16-episode second season on March 2.

New drama “Game of Silence” is set to air on Thursdays at 10 p.m. starting April 7, taking the timeslot currently occupied by “Shades of Blue.” The series revolves around four best friends who harbor a dark secret they thought was buried 25 years ago.
