The Athletics have fined Billy Butler and Danny Valencia after they were involved in a clubhouse fight last week that led to Butler being placed on the seven-day concussion list.

The San Francisco Chronicle reported Monday that Butler and Valencia began fighting over comments Butler made to an equipment representative prior to a game Friday at the Chicago White Sox. During the exchange, Valencia hit Butler in the temple before multiple teammates stepped in to end the altercation.

Butler sat out the series in Chicago with headaches and nausea.

A’s general manager David Forst says “from the organization’s standpoint, it’s resolved and we’re moving past it.”

Butler is a former Kansas City Royal and Valencia is a former Minnesota Twin.
