Dave Mason has canceled the remaining dates on his Traffic Jam 2024 tour to take care of an "urgent medical condition."

According to a press release, "doctors detected a serious heart condition during a routine appointment that requires immediate medical attention." The dates affected by the cancellations include Tuesday's appearance in Santa Barbara, California, and run through early November.

Mason's doctors "expect a full and successful recovery," and he plans to get back on the road in 2025. "I’m heartbroken to have to cancel these dates, but it's doctor’s orders," the 78-year-old Mason said. "I’ll be back, and better than ever, in 2025."

In the mid-'90s, Mason joined Fleetwood Mac after Lindsey Buckingham and Stevie Nicks exited the band. He played on one album, 1995's Time, and a tour. He was inducted into the Rock & Roll Hall of Fame as a member of Traffic.
