PHILADELPHIA — Boston Celtics guard Mickael Pietrus left the court on a stretcher and was hospitalized after an awkward collision late in the first half of Friday night’s game against Philadelphia. Pietrus was listed as having a questionable closed head injury.

Pietrus got tangled up with Philadelphia’s Lou Williams while driving to the basket and hit the floor hard trying to force a shot attempt. His back hit hard on the court and his neck appeared to whiplash. Pietrus immediately grabbed for the back of his head and rolled over onto his stomach. Trainers and medical staff soon rushed to assist him.

The game was delayed for 10 minutes while medical personnel attended to Pietrus. He was immobilized before being taken off the court.

It was a scary scene for a Celtics team that not only has lost two players this season to heart ailments, but also watched Marquis Daniels endure a similar-looking scare last season. Daniels, who had a pre-existing spine condition, was lost for the season and needed surgery before returning to the team this year.

Daniels was one of the players around Pietrus as he was assisted to on the floor.

Pietrus started in place of injured guard Ray Allen (ankle).

The Celtics lost another guard Friday night, as Avery Bradley left with a sprained left ankle.

Bradley appeared to tweak the ankle late in the first half and departed with 41.1 seconds to play in the second quarter.
