Kyle Okposo was diagnosed with the H1N1 swine flu yesterday and did not travel with the Islanders to Washington for their game tonight.

The team also learned upon arriving in Washington that Doug Weight, who also had the swine flu this season, will be out 4-6 weeks with an upper-body injury suffered on Friday against the Devils.

Weight was initially expected to be out only a week, but testing revealed a more serious injury.

The Islanders have suffered the most man-games lost to injury each of the past three seasons. They had been relatively healthy through the first 15 games, but Friday in Newark they lost defenseman Radek Martinek for the season with a torn ACL and Weight.

Okposo practiced on Monday - as a defenseman to give the team six for the practice. He arrived at IceWorks in Syosset to travel with the team, but was immediately sent to a doctor by trainer Garrett Timms.

Okposo has three goals and seven assists. Weight, who missed four games with a groin injury and swine flu before suffering this latest injury, has six assists in 11 games.

Trent Hunter (torn pectoral), whom coach Scott Gordon said would be a game-time decision tonight, may turn into a definite to play with Okposo out. Hunter, who's missed all but two games this season, skated in Okposo's spot on the right side with Frans Nielsen and Sean Bergenheim the last two days in practice.

"I feel like I'm ready," Hunter said. "It's just a matter of getting my body back in game shape."

Notes & quotes: Rick DiPietro practiced before the team's full workout for the second straight day and looked good, according to Gordon. The next step for DiPietro is to work Monday and Tuesday, rest Wednesday and work Thursday and Friday of next week.
