CBS today announced its primetime lineup for the 2019/20 season, unveiling a new time period for Young Sheldon.

Starting this fall, Young Sheldon will be inheriting the Thursday 8/7c slot of The Big Bang Theory, which ends its twelve-season run tomorrow.

Taking Young Sheldon's old 8:30/7:30c time period will be the new single-camera comedy The Unicorn. The seventh season of Mom, which was co-created by The Big Bang Theory and Young Sheldon's Chuck Lorre, retains its 9/8c time period. New multi-camera comedy Carol's Second Act, starring Patricia Heaton (Everybody Loves Raymond, The Middle) follows at 9:30/8:30c. The new drama Evil will close out Thursday nights at 10/9c.

THE UNICORN is a single-camera comedy about a tight-knit group of best friends and family who helps Wade (Walton Goggins) embrace his "new normal" in the wake of the loss of his wife one year ago. As a sometimes ill-equipped but always devoted single parent to his two adolescent daughters, he is taking the major step of dating again. To Wade's amazement, he's a hot commodity with women, and his friends explain that he's the perfect single guy - a "unicorn": employed, attractive, and with a proven track record of commitment. With his daughters and best friends rooting him on and hoping he'll find happiness again, Wade and his healing heart are ready to try life... and love... again. Bill Martin, Mike Schiff, Aaron Kaplan, Dana Honor, Wendi Trilling, Peyton Reed, and John Hamburg (pilot only) are executive producers for CBS Television Studios. Hamburg directed the pilot from a script by Martin and Schiff.

Emmy Award winner Patricia Heaton stars in CAROL'S SECOND ACT, a comedy about a woman who embarks on a unique second act after raising her children, getting divorced and retiring from teaching: pursuing her dream of becoming a doctor. At age 50, Carol is a medical intern and must sink or swim with peers who are half her age. It's her enthusiasm, perspective and yes, even her age, that may be exactly what will make her second act a great success. Emily Halpern, Sarah Haskins; Patricia Heaton, Adam Griffin, David Hunt and Rebecca Stay (Four Boys Entertainment); Aaron Kaplan and Dana Honor (Kapital Entertainment); and Pamela Fryman (pilot only) are executive producers for CBS Television Studios. Fryman directed the pilot from a script by Halpern and Haskins.

The second season finale of Young Sheldon airs tomorrow night at the later time of 9/8c after the series finale of The Big Bang Theory.

Young Sheldon will return for its third season this fall on CBS. The network has also renewed the show for a fourth season to air in 2020/21.

Young Sheldon's world is about to expand in a Big way as characters from The Big Bang Theory appear in the upcoming second season finale, TVLine has reported.

Younger versions of Sheldon's adult friends Leonard, Penny, Howard, Bernadette, Raj, and his future wife Amy will appear in next week's episode, "A Swedish Science Thing and the Equation for Toast".

It's not clear how the Big Bang characters will be introduced to the Young Sheldon universe with none of them living in Texas. Before they all came to live in Pasadena, the group was spread as far afield as Nebraska, New Jersey and India.

The Big Bang Theory and Young Sheldon had their first crossover last December when The Big Bang Theory's Sheldon watched a video tape from his childhood, featuring his father George (Lance Barber), brother Georgie (Montana Jordan) and his younger self (Iain Armitage).

The second season finale of Young Sheldon airs next Thursday, May 16 at the later time of 9/8c, right after the hour-long series finale of The Big Bang Theory.

Although The Big Bang Theory is coming to an end, CBS has already renewed Young Sheldon for another two years, taking the show through to its fourth season in 2020/21.
