The Indianapolis Star (Mike Wells) reports: The Indiana Pacers have gone from being optimistic that swingman Mike Dunleavy will soon return to the lineup from his right knee problems to wondering if he’ll play again this season. “I don’t know,” coach Jim O’Brien said when asked about Dunleavy’s status. “I know when they say he’s out indefinitely, there is a chance he can come back. When that is, this year? I’m not sure. I don’t feel like we have all the (medical) information available to make that determination yet.” … O’Brien continues to team Jarrett Jack in the backcourt with T.J. Ford in Dunleavy’s place.
