Ronald Tillery of the Memphis Commercial Appeal reports:

Grizzlies swingman Ronnie Brewer will miss at least three weeks with a partially torn right hamstring.

Brewer, who was injured Friday during the Grizzlies’ 100-87 double overtime loss to Miami, had his condition confirmed this morning after a magnetic resonance imaging exam.

Brewer did not travel this afternoon with the team to New Jersey where the Griz will face the Nets on Sunday evening. The Grizzlies are officially saying that Brewer will be out indefinitely and a timetable for his return will be set in a week.
