Chester Bennington, the vocalist for Linkin Park, has been hospitalized after suffering severe back and abdominal pains.

Bennington checked into a Los Angeles hospital on Friday. Doctors are currently trying to diagnose the nature of the ailment.

As a result of Bennington's illness, Linkin Park have canceled 12 European shows between June 7 and June 23, according to a European band spokesperson. Video plans have also been postponed.

There is no word yet on whether Bennington's condition will affect the band's participation in the Summer Sanitarium Tour, which begins July 4 in Pontiac, Michigan, and also features Metallica, Limp Bizkit, Deftones and Mudvayne (see [article id="1470135"]"More Dates Added To Metallica/ Limp Bizkit/ Linkin Park Tour"[/article]).
