The lower-body injury that forced Ducks goalie Ray Emery out of Wednesday's 6-2 victory over San Jose could make him questionable for Friday's potential playoff-clinching home game against the Kings.

Emery pulled himself out midway through the second period as the Ducks were about to go on a two-man advantage while holding a 3-1 lead. The immediate concern is whether the injury is related to the major hip surgery he underwent last April in order to resurrect his career.

"I don't think so," said Emery, who is 7-2 with a 2.28 goals-against average in nine starts.

Emery said he felt some tightness at the start of the second period and realized that it was best he not try to play through it with the team holding a two-goal lead.

"I felt a little bit of something a bit funny and kind of tried it out for five to 10 minutes there," he said. "I kind of told them that I thought it'd probably be best if I got out of there and took care of myself."

Ducks coach Randy Carlyle didn't elaborate on the source of Emery's injury. Dan Ellis finished the game as Emery returned the bench later in the second after a spell in the training room.

"His status is the same," Carlyle said. "He's got a lower-body injury that we're going to be very precautionary about. We felt that it was best for him to work out off ice and have a treatment this morning and we'll make an assessment tomorrow morning [after] the morning skate."
