The bassist insists he has not left Creed and Alter Bridge guitarist Mark Tremonti's band, but Van Halen's 2015 dates are a priority for him.

He says, "I am still part of Tremonti and very excited for the release of (new album) Cauterize, but unfortunately I am unable to participate in the upcoming tour dates, both in the States and overseas, due to my prior commitment with Van Halen.

"I look forward to seeing all of the Tremonti fans on the road as soon as my schedule permits!"

Van Halen will officially announce the North American dates during an appearance on U.S. chat show Jimmy Kimmel Live on Monday (30Mar15).
