Details of the altercation between A’s outfielder Danny Valencia and designated hitter Billy Butler emerged Monday, with Valencia facing possible discipline later in the day for his role in the incident. The physical confrontation between the two teammates left Butler unable to play in the weekend series at Chicago because of a possible head injury.
Two players who witnessed the event and helped break up the fight spoke to The Chronicle on the condition of anonymity because they didn’t want to appear to be taking sides. One said that Valencia and Butler both played roles in the incident: Valencia should not have punched Butler.
