ESPN Ticker on ESPN 2 just said Harrison is OUT for the Carolina game. Is that reliable?
Sad... This will probably be his last season.

What would make you state that? There is NOTHING out there (that I've seen) to even suggest this. The guy gets a nagging injury and you are ready to off his career?
In case you didn't notice, he's old...35. Second, he's been hampered by this injury for a few games now. When he wasn't injured, his production as compared to past years has dramatically declined. If he was wise, he would go out on top instead of dragging this out.
You willing to wager on this one? You are utterly speculating with no basis other than the fact that a guy is 35 and his injury has lasted "a few games now" - oh yeah, better get thee to a nursing home.35 is old, it is not ancient.
How did Marvin do last year? So it is not as if he is years removed from greatness. Marvin was off to a typical slow start and then got hurt. Again, there is no logical reason to jump to wont come back next season. It's an absurd thought without having anything to back it.
That said, he might want to refrain from Pre Game dunks over the crossbar.
