Mitchell gained recognition for his notable portrayal of Eric Green in the CBS drama Jericho, as well as for his role as Ralph Cox in the sports biopic Miracle.

Mitchell was married to fellow actor Susan May Pratt, and they had two children together, a daughter named Lilah and a son named Kallum.

Sadly, Mitchell's family has now announced his tragic passing.

Born in Toronto in 1974, Mitchell gained recognition alongside Kurt Russell in Miracle, portraying Ralph Cox, the last player cut from the 1980 Men's Olympic Hockey Team.

He gained further prominence after being cast in 2019's Captain Marvel, portraying the titular character's father, Joseph Danvers.

Mitchell portrayed three Klingon characters in Star Trek: Discovery, including Kol in season 1, Kol-Sha (Kol's father) in season 2, and Tenavik.

A statement from Mitchell's family has been released, announcing his tragic passing at the age of 49.

"With heavy hearts, we announce the passing of Kenneth Alexander Mitchell, beloved father, husband, brother, uncle, son and dear friend to many," his family's statement says.

"He lived by the principles that each day is a gift and that we never walk alone. His life is a shining example of how full one can be when you live with love, compassion, humour, inclusion, and community."

It adds: "Like a massive star exploding with kindness, purity and a particular brand of silly, you were pulled right into his orbit."

"Once captured, Kenny could bathe you in positivity, compassion, thoughtfulness, and hilarity, and make you feel so loved."

In their tribute, Mitchell's family remembers him as "a hope seeker, daydreamer, dream believer, soccer player, beach walker, bear hugger... and more than anything else, a proud father."

Following the star's passing, numerous official tributes swiftly emerged.

"The entire Star Trek family sends their condolences to Mitchell's family, friends, loved ones, and fans around the world," the official site reads.

Daredevil's Deborah Ann Woll writes: "I'm so sorry," while Scream's Skeet Ulrich says: "You will never ever be forgotten!! You are embedded in the hearts and minds of so many. You will always be an inspiration. All my love to you and your beautiful family."

In 2018, Mitchell received a diagnosis of amyotrophic lateral sclerosis (ALS), commonly referred to as Lou Gehrig's disease.

As his condition advanced, Mitchell transitioned to using a motorized wheelchair. In Star Trek: Discovery season 3, he portrayed Aurellio, a character whose reliance on a wheelchair-like device mirrored Mitchell's own battle with ALS.

"For five and a half years Ken faced a series of awful challenges from ALS. And in truest Ken fashion, he managed to rise above each one with grace and commitment to living a full and joyous life in each moment," his family's statement concludes.

By 2021, Mitchell had lost the ability to speak, as reported by Daily Star Trek News.

May you rest in peace.
