Glen Davis will be out for an extended period after injuring his right thumb in a private altercation with a friend, according to sources.

Sources said there is some type of fracture in the thumb and that he will have to undergo further testing with specialists to determine whether there is greater damage that could necessitate surgery.

The injury occurred Sunday night during the incident between Davis and a former teammate, who had flown up from Louisiana, sources said. According to sources, Davis was defending himself at the time.
