Source: Jonathan Baldwin hurt in fight

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.

Baldwin's agent, Rick Smith, refused to comment on the situation.

"Jonathan Baldwin did not play tonight due to injury. That's the extent about what I'm going to talk about," Chiefs coach Todd Haley said after Friday night's preseason loss to the Ravens, calling the incident "family business."

Chosen 26th overall, Baldwin started 27 games for Pittsburgh.

The 6-foot-4, 230-pounder averaged 18.31 yards per catch and finished ranked eighth all-time at Pitt with 2,325 yards receiving and 127 receptions.

Jones is entering his second season with the Chiefs.

After a career-high 1,402 yards in 2009 with the New York Jets, Jones served as Kansas City's No. 2 back last season, posting 896 rushing yards, while Jamaal Charles led the Chiefs with 1,467.
