CALGARY, Alberta — New York Islanders forward Kyle Okposo was removed from the ice immobilized on a stretcher after taking a big hit from Calgary Flames defenseman Dion Phaneuf early in the second period of a preseason game.

Okposo, the seventh pick in the 2006 draft, remained motionless on the ice for more than 6 minutes as he was attended to by trainers from both teams and other medical personnel.

A CT scan showed Okposo had a mild concussion, Islanders spokesman Seth Sylvan said in a text message to The Associated Press. Sylvan said Okposo accompanied the team on the flight to Saskatoon, Saskatchewan, where the Islanders are conducting training camp.
