Former San Francisco 49ers offensive lineman William "Bubba" Paris has been charged in federal court in Oakland with three misdemeanor counts of failing to file income tax returns.

Paris, 52, of Discovery Bay, was charged by federal prosecutors on Monday with willfully failing to file returns for the tax years 2006, 2007 and 2008.

He is scheduled to be arraigned before U.S. Magistrate Kandis Westmore in Oakland on March 4.

Paris played for the 49ers from 1983 through 1990, during a time when the team won three Super Bowl championships.

Paris now works as a motivational speaker, and is also a poet and an ordained evangelist minister, according to his website, www.bubbaparis.org.

The federal charges allege that the former football player received income of $57,187 in 2006; $83,856 in 2007; and $41,700 in 2008, but failed to file returns for those years.

If Paris is convicted, the maximum penalty for each count is one year in prison, but a judge would consider federal sentencing guidelines before determining a penalty.
