Bill Cosby's busy upcoming concert tour just got a little less busy.

Treasure Island Hotel and Casino in Las Vegas spiked his Nov. 28 show and will give ticket holder refunds. A casino rep said it was a "mutual agreement."

His appearance at Tuscon's Desert Diamond Casino has also been canceled. No reason was given by the casino for the canceled date, which had been scheduled for Feb. 15.

Finally, Cosby's April 11 performance in Champaign, Ill., has also been canceled. In that case, it was the theater's idea, not Cosby's.

"We made the call because we felt with increasing allegations, for our constituents, it was inappropriate to move forward with the show," a Virginia Theater rep told USA Today.

    In the past week, numerous allegations of sexual abuse by Cosby from a number of women have led to canceled interviews and NBC and Netflix projects. "The Cosby Show" also was pulled off the air on TV Land. Cosby issued a statement Sunday discrediting decades-old accusations and his attorney has denied four of the allegations.

    Thursday night he appeared in Bahamas at a benefit for a women's service organization.

    Including an appearance in Melbourne, Florida tonight, Cosby had been slated to perform at least 36 shows between now and May 2015.

    How many he performs remains to be seen.
