Okposo went to the hospital Sunday night and was still there Monday morning.
"We'll know a little bit more here in a couple of hours," Islanders coach Jack Capuano said after the morning skate. "We knew going in what time she was going to go in. We knew he'd be there all night. Now it just depends on this morning, if things work out well, knock on wood, he gets his proper rest and he can play tonight."
Islanders forward Josh Bailey will return to the lineup after missing four games with an upper-body injury. Capuano said he wants to see Bailey shoot more. He's had 12 games this season in which he didn't register a shot on goal.
"I need to see a guy that is going to get more pucks to the net," Capuano said. "We expect all our guys to play well defensively, but he's gotta be a guy who gets some pucks to the net. There's no question he's gone games where he's got no shots and he's gotta get back to doing that."
Here is the Islanders' potential lineup for the game Monday:
