Back in December, Antoine Walker was waived by the Memphis Grizzlies and wasn't picked up by another team. So what did he do with all that free time? It looks like he was gambling. According to the Associated Press, Walker is facing criminal charges over $822,500 in gambling debt to three Las Vegas casinos.

The Clark County District Attorney's office says that Walker is facing three felony counts of writing 10 bad checks totaling $1 million to Caesars Palace, Planet Hollywood and the Red Rock Resort. Apparently, Walked repaid $178,000 of that debt but is still on the hook for more than $800,000. He also owes the district attorney's office more than $82,000 in legal fees regarding the criminal charges. A warrant was issued for his arrest.

In Walker's 12-year career, he has earned more than $100 million. He has played for the Boston Celtics, Dallas Mavericks, Atlanta Hawks, Miami Heat and the Minnesota Timberwolves before being traded to the Memphis Grizzlies, which released him.
