INDEPENDENCE - It's do-or-do-summertime for the Cleveland Cavaliers.

One more loss, and a second straight Eastern Conference title is history.

One more win, and it's back to Chowderland for Game 7.

After squandering a 14-point lead at Boston in a hail of missed free throws and getting entangled by the Celtics' spiderweb-like defense in Game 5, LeBron James and his teammates are down 3-2 and facing elimination from the NBA playoffs on Friday night at Quicken Loans Arena.

They'll go into Game 6 shorthanded.

Guard Daniel Gibson, one of the club's best perimeter shooters and a star in last year's postseason, separated his left shoulder going for a loose ball early in the fourth quarter of Game 5 and will need a minimum of one week to recover.

The Cavaliers may be done before he's well.
