Bayless leaves with ankle sprain

Portland guard Jerryd Bayless, who started in place of the injured Brandon Roy Friday night in Boston, left in the third quarter with a sprained left ankle and did not return.

Bayless played 21 minutes in the Blazers' 98-95 loss to the Celtics, recording 12 points and four assists before suffering the injury.

Roy has been ruled out for Portland's next four games after re-aggravating a right hamstring injury against the Philadelphia 76ers on Wednesday night.

Bayless is averaging 8.8 points and 2.3 assists for the year.
