Nickelback have been forced to cancel all remaining tour dates of their 2015 North American tour, due to frontman Chad Kroeger being diagnosed with an operable cyst on his voice box. Kroeger will undergo surgery in three weeks.

Kroeger said in a statement, “I am sorry I have to interrupt the party this summer and I am definitely not thrilled with the prospect of being silent for many weeks to come when I could be out there playing for our fans. I am relying on my doctor and his team to help get my voice back in good form as quickly as possible.”
