Thursday’s brawl in San Diego will cost Dodgers pitcher Zack Greinke eight weeks on the disabled list because of a broken left clavicle.

Greinke was examined by team Dr. Neal ElAttrache today in Los Angeles and underwent a CT scan on his left clavicle. It was determined that he should undergo surgery to place a rod in the clavicle to stabilize and align the fracture.  The surgery will be performed tomorrow by ElAttrache and team Dr. John Itamura at White Memorial Hospital in Los Angeles.

Both teams’ benches and bullpens emptied twice on Thursday — once when Quentin charged the mound after being hit by a Greinke fastball in the sixth inning, and again when Dodgers utilityman Jerry Hairston Jr. rushed toward the Padres’ dugout after the initial fracas calmed down. Greinke suffered the injury either when Quentin initially bull-rushed the pitcher and collided shoulder-to-shoulder, or when Greinke was tackled to the ground seconds later.

The Dodgers, who play the Arizona Diamondbacks tonight in Phoenix, placed Greinke on the 15-day disabled list and recalled Shawn Tolleson from Triple-A Albuquerque.

It is expected that either Chris Capuano or Ted Lilly will replace Greinke in the rotation. His next start was expected to fall Tuesday against the Padres, who visit Dodger Stadium for three games beginning Monday.

Monday is also “Jackie Robinson Day” across Major League Baseball. Commissioner Bud Selig is expected to attend the game at Dodger Stadium.

The video of the brawl (watch it here) has been replayed often, with no shortage of opinions on who to blame or how severely to punish Quentin. An informal poll on this website shows that the majority of readers agree with Dodgers manager Don Mattingly: Quentin shouldn’t play as long as Greinke is sidelined.
