Rage Against The Machine has officially canceled the U.K. and Europe leg of the band’s Public Service Announcement reunion tour due to Zack de la Rocha‘s leg injury, which happened on stage in Chicago at the second show of the tour.

De la Rocha powered through the remainder of RATM’s Chicago concert after hurting his leg and has performed every subsequent show seated on a road case (I guess Dave Grohl’s broken leg throne wasn’t available). De la Rocha has shown admirable resilience as he has continued the tour, but the band announced on Thursday that he “has been advised that the August and September 2022 UK and European leg of the Rage Against The Machine tour cannot proceed.”

Rage Against The Machine will finish out its long-awaited five-night run at Madison Square Garden this week. After that, the announcement explained, “Zack must return home for rest and rehabilitation. The flights, travel time, and rigorous schedule in the UK and Europe are simply too much of a risk for a complete recovery.”

The band added, “It is with great disappointment that we announce this cancellation. … We are so sorry to all of our fans who have waited years to see us and hope to Rage again soon.”

Those with tickets to see Rage Against The Machine in the U.K. and Europe should contact their point of purchase for refunds to any headline shows. As of now, Rage Against The Machine’s 2023 U.S. tour dates, which are scheduled to kick off in Las Cruces, NM on February 22nd, remain unaffected.
