According to the search results, Kiko Loureiro, the lead guitarist of Megadeth, will not be joining the band on their upcoming tour due to a family emergency. He will be temporarily replaced by Teemu Mantysaari. Loureiro himself confirmed that he needs to be home with his children to help them face the difficult challenges that arise from him being a "Dad that works away from home". The situation is temporary, and Loureiro is expected to return to the band after the family matter is resolved.
