Rossovich is possibly more recognizable for his TV roles, principally as Dr. John 'Tag' Taglieri, the surgeon who left Nurse Hathaway at the altar in the final episode of the first season (1994-95) of "ER". On Rossovich's first series, he was Geller, a cop, in the short-lived "MacGruder and Loud" (ABC, 1985), and Spud in the equally short-lived primetime serial "Sons and Daughters" (CBS, 1991). In 1995, he started his first of three seasons starring as Lt. Palermo, the head of a team bike patrol officers in the USA Network series "Pacific Blue". He also made occasional appearances in TV longforms, including "Luck of the Draw: The Gambler Returns" a 1991 NBC miniseries.
