Drummer Danny Carey tore a bicep last weekend and underwent surgery February 21.

The band said he is recovering well and the rescheduled tour dates will be announced shortly.

The group, which has been touring almost constantly since releasing 10,000 Days last April was scheduled to launch its first U.S. trek of the year with two shows in Las Vegas March 15-16.

The original routing included stops at nearly 30 arenas and stopped in many cities the band did not cover on its last North American trip.

Tool is still scheduled to headline at Bonnaroo, which takes place June 14-17 in Manchester, Tenn.
