Neither Keiser or the man he was fighting sustained any serious injuries, but Keiser was taken into custody and booked nonetheless. The fight happened the same night the Chargers clinched a playoff berth by beating the Kansas City Chiefs 27-24 in a controversial overtime win.
Keiser was bailed out after having to post $8,000, according to records. The organization says it is aware of the situation but declined to go into further details.
It will be interesting to see if the Chargers hand down any discipline before their biggest game of the year on Sunday against the Cincinnati Bengals, although a suspension is not expected. Keiser has been one of San Diego's better defensive players, racking up 4.5 sacks to finish second on the team.
