The By the Way rockers were due to perform in Denver, Colorado on Thursday night (02Mar17) but the band issued a statement on their website earlier that day announcing they had postponed the show and two other upcoming concerts so Anthony can recover from the infection, which causes inflammation of the airways in the lungs.
"We are so sorry that we cannot come to Denver, Glendale and San Diego as planned," the statement reads. "Anthony has been fighting off the bronchitis all week and still needs a few more days to recover. We are sorry for any inconvenience to our fans and look forward to seeing you."
Drummer Chad Smith also posted an apology on Twitter, writing, "Sorry guys n gals. AK has bronchitis. Be back soon."
They were due to perform in Glendale, Arizona on Saturday (04Mar17) and in San Diego, California on Sunday (05Mar17). The latter show has been rescheduled for 21 March (17) while the other two have been pushed back until October (17).
The band are currently scheduled to return to performing for their three dates at the Staples Center in Los Angeles from Tuesday (07Mar17).
