A Calgary woman is recovering from a long list of injuries she suffered when she was knocked to the ground by an unknown assailant in what she believes was a ‘knockout game’.

Chelsea Curran was leaving a nightclub in downtown Calgary earlier this month with some friends to look for a cab when a car pulled up to the curb.

She says a man jumped out, punched her, and then took off.

As a result Curran’s head struck the pavement, leaving her with two black eyes, a concussion, and whiplash.

She says she has no idea why anyone would target her, and wonders if she was a victim of the so-called ‘knockout game’ – a disturbing prank popularized in online videos where people punch victims unexpectedly.

Curran says she’s speaking out in the hopes of protecting others from future attacks.

“I just don’t want it to happen to anyone else. It’s been a pretty crappy couple of weeks. If I can prevent it, bring some light to it, so they maybe cool off or something.”

The attack was reported to police, but Curran says she hasn’t heard anything back about any progress in the investigation.
