[ESPN.com] A locker-room fight between veteran Chiefs running back Thomas Jones and first-round draft pick Jonathan Baldwin has left the rookie receiver doubtful for the rest of the preseason with a wrist injury, a team source confirmed Friday to ESPN NFL Insider Adam Schefter.

The Kansas City Star’s Adam Teicher is also confirming this report, and he adds that the Chiefs will address this situation after tonight’s game at Baltimore.

Baldwin was mysteriously absent Wednesday from the Chiefs’ last training camp practice in St. Joseph. The Chiefs have given no public explanation for his absence and his agent, Rick Smith, has not returned repeated messages.
