The band's drummer Chad Smith aggravated an old injury that had not healed while playing the Olympia in Paris last week and is since suffering from a tear of various tendons in the shoulder and upper arm/biceps.

He had an MRI that revealed the injury and waited to see if he could play last week. After the band had already cancelled the Madrid show to allow Smith time for evaluation in Paris he came to Italy hoping to play the remainder of the shows.

After the weekend shows Smith was in pain again and it was obvious that his condition is not good enough to continue without further medical attention and immediate rest. This is why this week's sold out Hamburg and Copenhagen shows were cancelled to allow Chad more time to see specialists in London.

All recent shows have shown Satriani, Anthony, Hagar and Smith at top form and with Smith being a very physical drummer who cannot play a show at 50% it is very hard for him to hold back onstage. He is very sorry he cannot play for the German and Danish fans this week.
