The ‘CSI’ triple crossover (various times and dates): Just follow the bouncing actor.

The ‘CSI’ triple crossover (various times and dates): Just follow the bouncing actor. This week Laurence Fishburne racks up the frequent-flier mileage as his character, Dr. Ray Langston, gets involved in a three-episode story arc that takes him to Florida (“CSI: Miami”), the Big Apple (“CSI: NY”) and back to Las Vegas (“CSI”). It all begins when a severed leg found in the Everglades is linked to a missing girl from Las Vegas. Eventually, Langston and his cohorts find themselves probing a case tied to human trafficking and black-market organ harvesting. The “CSI” franchise has done crossovers before, but this is the first time it has followed a case across all three shows. “CSI: Miami” 10 p.m. Monday; “CSI: NY” 10 p.m. Wednesday; “CSI” 9 p.m. Thursday, CBS.

“How I Met Your Mother” (8 p.m., CBS): You knew it had to happen. On “How I Met Your Mother,” the romance between Barney and Robin hits a rough patch, and Lily devises a scheme to break them up. Alan Thicke guest-stars.

“Lopez Tonight” (11 p.m., TBS): The face of late-night TV continues to change as “Lopez Tonight” has George Lopez rocking his own gab fest. The comedian promises to bring a lively street party atmosphere to the genre.
