Tyler Duckworth, a reality TV competitor and two-time winner of MTV’s “The Challenge,” has died at age 44. Multiple outlets report that his death is announced after his passing earlier in the week, and that fans and cast members respond with tributes.

Duckworth first appeared in MTV’s “The Real World: Key West” before later competing on multiple seasons of “The Challenge.” Deadline and Variety note he competes across six seasons and wins twice. Both also say his mother, Joni Duckworth, announces his death on Facebook. The Hollywood Reporter similarly points to his start with “The Real World: Key West” in 2006, placing him within the broader MTV franchise.

Outlet accounts differ slightly on timing and setting details. The New York Post describes the death as sudden and references Tuesday, while Variety and Deadline say he died earlier in the week and that the cause of death has not been confirmed. Variety also reports his death occurred in North Dakota.
