1) “Saturday Night Live,” 11:29, NBC. One quick route to being an “SNL” host seems to be portraying Elvis Last season had Austin Butler, the “Elvis” star; tonight is Jacob Elordi, the “Priscilla” (shown heee) co-star. (He also did “Euphoria” and the “Kissing Booth” movies.) “SNL” had eight new episodes in 10 weeks, before airing four straight reruns. Now it’s back; Renee Rapp is the music guest.
2) Football. The second round of the pro play-offs begins, with the Texans and Ravens, at 430 p.m. ET on ABC and ESPN. Then (at 8:15 p.m. on Fox), the top-seeded 49ers play the surprising Packers. In their first season without Aaron Rodgers, the Packers were 6-8, then won four in a row, leading the Cowboys by as many as 32 points.
3) “Will Trent,” 8-11 p.m., ABC. The second season doesn’t start until Feb. 20, but here are the first three episodes (good ones) from the first year. Ramon Rodriguez plays Wiill, a quiet loner and a smart detective, with Erika Christensen as the cop who’s sometimes his lover. The first two hours probes the kidnapping of the daughter of a guy (Mark-Paul Gosselaar) who shares Will’s troubled past.
4) “Wiild Cards,” 8 p.m., CW. If you missed the series debut Wednesday, catch this quick rerun. Vanessa Morgan (who was Toni on “Riverdale”) is a delight as a good-hearted grifter; Giacomo Gianniotti (DeLuca on “Grey’s Anatomy”) plays the cop who’s reluctantly working with her. That’s followed by a rerun of the sub-par “Family Law” season-opener.
5) ALSO: NBC reruns its “fantasy league” spin-off of “America’s Got Talent,” from 8-10 p.m. And CMT has Steven Spielberg’s great “Raiders of the Lost Ark” trilogy at noon, 3 p.m. and 6 p.m., with the first two rerunning at 9 and midnight.
