Actor Jonathan Majors has avoided jail for assaulting his ex-girlfriend after he was sentenced to probation in a high-profile case that derailed the once-promising star’s career.

The 34-year-old star of Creed III and other films had faced up to a year behind bars after he was convicted of misdemeanour assault by a Manhattan jury in December.

Judge Michael Gaffey also ordered Majors to complete a year-long in-person intervention program. He also has to continue with his mental health therapy.

Following the guilty verdict, Majors was immediately dropped by Marvel Studios, which had cast him as Kang the Conqueror — a role envisioned as the main villain in the entertainment empire’s movies and television shows for years to come.

The conviction stemmed from an altercation last March in which Majors’ then-girlfriend Grace Jabbari accused him of attacking her in the back seat of a chauffeured car, saying he hit her head with his open hand, twisted her arm behind her back and squeezed her middle finger until it fractured.

Majors claimed the 31-year-old British dancer was the aggressor, flying into a jealous rage after reading a text message from another woman on his phone.

He maintained he was only trying to regain his phone and get away from Ms Jabbari safely.
