San Diego Chargers linebacker Thomas Keiser was arrested on Sunday night on suspicion of misdemeanor battery, according to U-T San Diego. The arrest happened just hours after the Chargers beat the Chiefs to claim the final wild card berth in the AFC. Keiser was at a bar in the Gaslamp Quarter of San Diego when he got into an altercation that eventually turned into a fight. "We're aware of the issue involving Thomas," the Chargers said in a statement. "We'll continue to monitor the situation and let the legal process run its course." The incident is still under investigation, but San Diego Police Captain Dino Delimitros did provide a few details to the Associated Press. "He got in a fight with somebody, the bouncers got involved, the police came up and somebody demanded a citizens' arrest," Delimitros said. Keiser's bail was set at $8,000, according to U-T San Diego, and he was released at some point on Monday.
