Here is the press release from MLB concerning the suspension of Kevin Youkilis and Rick Porcello for their roles in the altercation at Fenway Park on Tuesday night.

Discipline has been issued to three members of the Detroit Tigers and the Boston Red Sox as a result of the on-field incidents that occurred in the Tuesday, August 11th game at Fenway Park in Boston. Bob Watson, Vice President of On-Field Operations for Major League Baseball, made the announcement.

Tigers pitcher Rick Porcello has been suspended for five games and fined an undisclosed amount for intentionally throwing pitches at Boston’s Victor Martinez in the bottom of the first inning and Kevin Youkilis in the bottom of the second, which contributed to the incitement of the bench-clearing incident in the second inning. Porcello’s five-game suspension had been scheduled to begin tonight, when Detroit continues its series at Boston, but he has elected to file an appeal. Thus, his suspension will be held in abeyance until the process is complete.

Red Sox first baseman Kevin Youkilis has been suspended for five games and fined an undisclosed amount for charging the mound, throwing his helmet at Porcello and inciting the bench-clearing incident. Youkilis’ five-game suspension had been scheduled to begin tonight, but he has elected to file an appeal. Thus, his suspension will be held in abeyance until the process is complete.

In addition, an undisclosed fine has been issued to Tigers pitcher Edwin Jackson for his aggressive actions during the bench-clearing incident.

Note: At the time of this MLB press release, Youkilis was going to appeal the suspension. He has since changed his mind and began serving his suspension tonight. He’ll be eligible to return on August 18th when the Red Sox are in Toronto.
