When The Night Shift comes back for a fourth season, it will be without original cast member Ken Leung. I hear he had an option in his contract not to return. He was invited to continue but decided to pursue other opportunities instead.
据悉《夜班医生》第四季卡司Ken Leung将不再回归。据说是他合约中含有他不回归的理由。虽然受邀但他选择尝试其他的演出机会。

Leung, who has been on the show since the pilot, played Dr. Christopher “Topher” Zia, an emergency room doctor who previously helped soldiers who were injured in battle.
Leung是本剧的元老级演员了，他饰演Christopher “Topher” Zia医生，是急诊室优先为战争中的伤员诊治的医生。

The Night Shift,originally slated for midseason 2014, launched that summer, exceeding ratings expectations and earning a second season renewal. Season 2 aired in midseason 2015, with Season 3 returning to summer this year. The show produced 8 episodes in Season 1, 14 in Season 2, 13 in Season 3, with the same order expected for Season 4.
《夜班医生》首季是在2014年夏季档推出的，比预想的收视要好就获得了第二季的续订。第二季是在2015年的夏季档，很自然地，第三季是在今年的夏季回归的。本剧第一季共8集，第二季12集，第三季14集，第四季将和第三季的集数一样。
