Kevin Garnett isn't traveling with the Brooklyn Nets for Friday night's game against Boston, preventing his still-strong legion of Celtics fans from showering him with praise at the TD Garden one last time.

The 37-year-old forward is dealing with back spasms that will sideline him for a fourth straight game.

And while he's expected to return to action at some point, it remains to be seen if this was the last chance Celtics fans will get to see Garnett play at the TD Garden.

Garnett does have another year left on his contract, but he has maintained repeatedly that retirement is always an option under consideration at this point in his illustrious, Hall of Fame-bound career.

Indeed, Garnett might be closer to calling it quits than ever after what has been a turbulent season filled with injuries and inconsistent play at times which has left Brooklyn fighting an uphill battle to win most nights.

This season, Garnett has averaged 6.7 points and 6.7 rebounds per game, both career lows.

Brooklyn (30-29) comes in having won four straight, with wins in the last three coming as Garnett rests his back.

But there's no mistaking that Garnett, even on the downside of his NBA career, can still make difference-making plays.
