Kyle Okposo couldn't complete Friday's practice due to a lower-body injury. Okposo is day-to-day as a result. With him sidelined, that means the Islanders have lost their entire top line, including John Tavares (knee) and Thomas Vanek (traded). For Okposo, this is an unfortunate setback in what has been a great season. He's broken out with 27 goals and 69 points in 69 games this season.
