Osaka Evessa power forward Lynn Washington, the bj-league's 2010-11 All-Star Game MVP on Sunday, sustained a grade-two hamstring injury during Tuesday's practice. He's expected to be sidelined for two to three weeks.

Washington is the league's second-leading scorer (21.2 points) and tied for ninth in rebounds (10.2). He helped the Evessa (17-9) finish the first half of the season with the best record in the Western Conference.

The Indiana University product has played for Osaka since the team joined the bj-league in 2005, including titles in its first three seasons.

The Evessa play host to the Sendai 89ers, a perennial playoff club in the Eastern Conference, on Saturday and Sunday.
