PORTLAND, Ore. — The Lakers got good news tonight when the Portland Trail Blazers announced guard Brand Roy would sit out the next three games plus the All-Star game because of a right hamstring injury. He had missed 11 of Portland’s last 12 games going into tonight’s contest against the Lakers, who have lost nine in a row at the Rose Garden. “Unfortunately, I’m not where I was hoping I would be physically at this point,” Roy said. “It’s a setback and I’m obviously disappointed, but my entire focus is getting back on the court, contributing and helping our team down the stretch.” Roy scored 32 points in the Blazers’ victory over the Lakers here last month. He is averaging 23.1 points in 40 games.
