Graham Nash [ tickets ] of Crosby, Stills, Nash and (sometimes) Young fame broke both of his legs in a freak boating accident in Hawaii on Sunday (9/12), according to his manager.

``Graham was on a power-boat when it hit a large wave causing him to be thrown upwards,'' Gerry Tolman said in a statement. ``As he was coming down, another wave hit the boat and he landed very hard on the inside of the boat.''

Nash underwent surgery for two broken legs throughout the night, and was ''resting comfortably'' in an undisclosed hospital on Monday.

There's no word if Nash's injury will cause him to miss a planned reunion at the Bridge School Benefit with David Crosby, Stephen Stills and Neil Young Oct. 30-31.

A CSNY reunion tour -- which was pushed back from July -- is tentatively set to launch in January, and it wasn't immediately known if Nash's injury will cause a further delay. A new album titled ''Looking Forward'' is tentatively scheduled for release on Reprise Records on Oct. 26.
