The hits keep coming for former NBA star Antione Walker.  According to TMZ: “Antoine Walker’s NBA Championship ring for the bargain basement price of $21,500.

Antoine Walker’s NBA Championship ring just sold for $21,500 … which would have been great news for Antoine, if he wouldn’t have been FORCED to sell as part of his bankruptcy case.

Walker — who won the ring as a member of the 2006 Miami Heat — filed for bankruptcy back in 2010 … claiming he racked up more than $12.7 million in debts … but had only $4 mill in assets.

According to court docs, Walker had to liquidate his property to pay back his creditors  … including his ring. Now TMZ has learned, the ring has been tentatively sold to a guy named Andres Garcia for a cool $21,500.

We feel bad for Antione and hope things will start going his way again soon.
