Wow people. Really?!  Such a shame. I love my team more than anything, but shootings & beatings over your team is just crazy.  Relaxxxxxxx!

The San Francisco 49ers and Oakland Raiders will end their annual preseason matchup as a result of the violence at Saturday’s game, the San Jose Mercury News reported Monday, citing a high-ranking NFL source.

The source told the newspaper that both the NFL and local police are in favor of ending the preseason rivalry game.

On Monday San Francisco Mayor Ed Lee denounced the violence at the game at Candlestick Park, saying he witnessed some of the brawls himself as he sat in the stands.

Lee said Monday that he watched with horror as he saw several confrontations among fans. He called the behavior irresponsible.

Two men were seriously injured in the violence during and after the game on Saturday night. One victim was shot several times, while the other was beaten unconscious.

The public information officer at San Francisco General Hospital and Trauma Center said both patients brought there, a 26-year-old assault victim and a 25-year-old gunshot victim, were upgraded to fair condition Monday.

A number of videos have popped up online showing some of the brawls.

Lee says he’s working with police and the 49ers to review the tapes and identify people involved in the fights.

The Bay Area Newsgroup, citing a source familiar with the police investigation, reported that Saturday’s violence is suspected to have been sparked by friction between the Nortenos and Surenos gangs.

49ers president Jed York said in an appearance on KNBR radio in San Francisco on Monday that there was more security than usual for Saturday’s game and there will be even more security for Saturday’s game against the Houston Texans.
