Allen sits out Friday practice

Ray Allen was the only non-participant in the Celtics’ practice on Friday. The team watched film for roughly 30 minutes and then spent two hours on the court at their training facility in Waltham.

Allen, still hobbled by his sore right ankle, did some light shooting before practice and some free-throw shooting at the end, but was otherwise not involved.

Greg Stiemsma, who has sat out practices recently due to foot and knee ailments, did participate. Coach Doc Rivers said Thursday that Stiemsma would practice one of the two days before the team leaves for Atlanta.

Paul Pierce, who had left the regular-season finale on Thursday night with a sprained left big toe, also practiced. Pierce said it was a minor problem and he didn't expect it to hinder him in the playoffs.

The Celtics are scheduled to practice Saturday and then fly to Atlanta around 3 p.m.

Game 1 of their best-of-seven, first-round series against the Hawks is Sunday night at Philips Arena. Game 2, also at Philips, is Tuesday night.
