Blink 182 have canceled a series of tour dates after Travis Barker had to undergo emergency surgery.

The "All the Small Things" band's drummer had have an urgent medical procedure on his tonsils, forcing them to cancel all further shows in their current US tour, which runs until the end of the month.

"The band apologizes for any inconvenience as a result of these cancellations and thanks their fans for their ongoing support," a statement on the band's website reads. The note added Travis' "recovery period is expected to extend beyond the scheduled tour dates."

It is not yet known if the band's later dates in the UK and Europe, starting in June, will be affected by Travis' condition. The group - which also includes Mark Hoppus and Tom DeLonge - have already had to reschedule their tour once, after it was originally supposed to start in July last year, but dates were pushed back in order to allow the group to finish sixth album Neighborhoods.
