The bassist for Slipknot was rushed to the hospital by ambulance in the middle of the band's performance.

Alessandro "V Man" Venturella got onstage with the band Sunday night in Hartford, Connecticut but after a few songs the band abruptly stopped and went backstage. They returned minus V Man, and lead singer Corey Taylor told the audience, "I'm sorry to say that our bass player, Alex, had ... something happened."

We've learned Alex was rushed to the hospital for convulsions. It's unclear what his condition is this morning. The band continued its performance.

Slipknot's original bassist, Paul Gray, died in 2010 from an OD.
