Eagles guitarist's Parkinsonism diagnosis forces him into retirement

Since his diagnosis, the 72-year-old musician has experienced "performance issues."

"It is with profound regret that, due to performance issues associated with my recently diagnosed Parkinsonism, I find that I must bow out of my role with the Eagles while I can still do so gracefully," Smith told Fox News Digital in a statement. "It's been a great quarter of a century, and I had hoped to be able to finish out this year with the band, but I must now do what's best for all concerned."

Founding member Don Henley reacted to Smith's retirement in a statement shared with Fox News Digital.

"The Eagles will be forever grateful for the extraordinary talents that he brought to both our recordings and live performances," Henley said.

"Steuart will be greatly missed, but he will always be a part of our musical family. We know our many fans join us in wishing him well."

Guitarist Chris Holt replaced Smith beginning Jan. 17, the outlet reported. Smith performed with the group for the first part of the residency, Sept. 20 through Dec. 14.

The decision to fire Felder was made by Frey and Henley. The musician responded by suing the band for wrongful termination and the group eventually settled outside of court.

Before teaming up with the Eagles, Smith was known for his work with Rosanne Cash, Shawn Colvin, Rodney Crowell and Wynonna Judd.

The band currently consists of Henley, Joe Walsh, Timothy B. Schmit, Vince Gill and Deacon Frey.
