According to reports, Baldwin and Jones were involved in altercation after practice Friday, leaving Baldwin with an injured wrist that will keep him out of the remainder of the preseason.
Both of the players involved in the fight have a history of off-field antics.
Baldwin was labeled a character-risk coming out of Pittsburgh after being charged with disorderly conduct and harassment in 2009. The Chiefs overlooked those issues and took Baldwin with the 27th overall pick in last April's NFL draft.
Jones has also had issues with teammates in the past, as National Football Post's Brad Briggs points out. Back when he was with the Chicago Bears, Jones apparently punched fellow running back Cedric Benson in the head during a practice.
There has been very little coming from the Chiefs camp about the issue besides confirming that an altercation did take place and that Baldwin had injured his wrist. Reasons for the fight are unknown at this time.
But it's not totally out of this world to speculate that Baldwin's attitude had something to do with setting Jones off.
Baldwin essentially threw his coach under the bus at Pittsburgh, and his attitude towards the program was something teams questioned in depth during the draft process. It's entirely possible that something along these lines pushed Jones over the limit and he acted accordingly.
Still, it was a poor choice of timing for both parties.
The Chiefs are counting on Baldwin, a 6'4", 230-pound receiver, to contribute to a passing offense that ranked 30th in the NFL last season. Missing preseason games will only slow his progression into that role.
Jones, who is in his second year with the Chiefs, is fighting Jamaal Charles for carries in Kansas City's backfield. At 36 years old, his opportunities are dwindling.
It's yet to be seen what kind of repercussions will come from this fight, but it's clear that Baldwin's short NFL career has gotten off to rocky start.
