Former Weezer bassist Mikey Welsh has died at the age of 40. The musician died in Chicago yesterday, according to a report from The Chicago Tribune. Welsh is suspected to have died from a drug overdose.

Weezer took to their Twitter account to express their sadness over Welsh's passing, writing, "We are shocked and deeply saddened to hear the awful news, our friend and fellow weez rocker @mikeywelsh71 has passed away. We love u Mikey."

Welsh played with Weezer from 2000 to 2001. He appeared on the band's second self-titled album, which has also been referred to as 'The Green Album,' helping to record and perform hits like 'Hash Pipe' and 'Island in the Sun.' He left the group in 2001 after suffering a mental breakdown and decided to shift his attention towards a career in painting.

Strangely, Welsh actually posted a tweet about his death approaching on Sept. 26. He wrote, "dreamt i died in chicago next weekend (heart attack in my sleep). need to write my will today ... correction - the weekend after next." Welsh also posted a picture to his Facebook, saying that he was planning on seeing his friends from Weezer while he was visiting Chicago.

Welsh is survived by his wife and two children. Rest in peace, Mikey Welsh.
