Buehrle cautioned about motorcycle

INDIANAPOLIS -- Chicago White Sox general manager Ken Williams said he texted pitcher Mark Buehrle to warn him about being careful on his new motorcycle.

The bike was a gift from Buehrle's wife, Jamie, to commemorate his perfect game on July 23 against the Tampa Bay Rays.

The motorcycle was custom made as part of TLC's "American Chopper" television show in November.

Baseball contracts do not prohibit players from riding motorcycles. Every standard contract states that if a player hurts himself to the point where his play is impacted, the contract can be voided.
