The Indiana Pacers don't know whether George Hill will play Saturday night in Game 6 against New York.
It's not something they can worry about.
Instead, coach Frank Vogel is tweaking lineups and making adjustments just in case Hill can't pass his concussion tests before tip-off, and the Knicks are preparing as if Indiana will have its starting point guard back in the lineup.
NBA rules require players to feel symptom-free at rest and symptom-free when they are under exertion, too, before a team doctor can determine that the player is ready to return from a head injury.
With Hill, the Pacers took a 3-1 lead in the best-of-seven series. Without him Thursday night, the Knicks kept their playoff hopes alive with an 85-75 win at Madison Square Garden.
