Mark your calendars, 9-1-1 fans, because two of the 118 and 126’s finest will be making an appearance on Instagram together this weekend!
Oliver Stark, who portrays firefighter Evan “Buck” Buckley on FOX’s first responder series 9-1-1, announced today that he and 9-1-1: Lone Star‘s Ronen Rubinstein, who portrays firefighter T.K. Strand, will be going live this Sunday at 3 p.m. EST/12 p.m. PST.
Stark dropped the news on his Instagram Story, where he explained that he and Rubinstein will be appearing together on Instagram Live on January 31 to discuss the upcoming 9-1-1 and Lone Star crossover event. They’ll also be answering some fan questions as well.

The highly anticipated crossover event will take place on Monday, February 1. As a result of the massive wildfire seen in episode 2 of Lone Star, Buck, Hen, and Eddie will travel from Los Angeles to Austin to assist the 126. The storyline will begin some time during the 9-1-1 episode “Future Tense,” which airs on FOX at 8 p.m. ET/PT. The episode synopsis states that the 118 will be prepping for an out-of-state mission, amongst other things. The bulk of the event, however, will take place in the second hour starting at 9 p.m. ET/PT during the 9-1-1: Lone Star episode “Hold the Line.” Go here to watch the latest preview for the crossover.
Stark also appeared in the first episode of FOX’s new TMI series with Lone Star‘s Rafael Silva today.
