The AP reports: Even without All-Star guard Brandon Roy, the Portland Trail Blazers earned an impressive win Tuesday night. Steve Blake had 21 points, LaMarcus Aldridge added 20 and the short-handed Blazers beat the Boston Celtics 91-86, sending the NBA champions to their third loss in four games… Reserve forward Travis Outlaw had 17 points for Portland and Greg Oden added 13 points and 11 rebounds despite injuring his ankle in practice Monday. Paul Pierce scored 28 points, making 14 of 15 foul shots, and Kevin Garnett had 17 points and eight rebounds for the Celtics (28-5), who were at the end of a four-game road trip and have more losses since Dec. 25 than in the previous two months of the season… Rajon Rondo had 13 points, seven assists and six rebounds for Boston.

There was a controversial play late in the second quarter when the Trail Blazers scored while using six players on the court. The basket counted, but a technical foul resulted in a free throw for the Celtics. More details here.
