KANSAS CITY, Mo. (AP) Pro Football Hall of Fame Member Ron Mix faces up to three years in federal prison after pleading guilty in Missouri to a felony tax-fraud charge.

The Kansas City Star (http://bit.ly/1WL4tFJ ) reports Mix agreed to pay nearly $50,000 to the Internal Revenue Service under his guilty plea Monday in Kansas City to one count of making false statements in a tax return.

Authorities say Mix was a San Diego-area lawyer who illegally paid a non-lawyer for referrals on clients and donated about $155,000 over three years to a charity operated by that person. Prosecutors say Mix then claimed those payments as charitable deductions.
