WALTHAM, Mass. — Veteran point guard Carlos Arroyo participated in his first practice on Tuesday with the Boston Celtics after being signed to a minimum, prorated contract for the remainder of the season.

Arroyo is expected to be available today when the Celtics play the Los Angeles Clippers.

“He played against us in two playoff series. He should know some of our stuff. That’s the way we look at it,” Boston Coach Doc Rivers said.

“But he’s a point guard, been a point guard all his life. So I think some of the stuff, he’ll pick up pretty quickly.

“All the nuances of things, that’ll just take time.”

Rivers said guard Delonte West, who has a sprained right ankle, will not play against the Clippers, and forward Glen Davis, who has patellar tendinitis, is out for two more games.
