Former NFL and Kansas defensive lineman Dana Stubblefield has pleaded guilty to lying to investigators in the BALCO steroids case. He's the first football player accused in the federal investigation.

The plea deal calls for him to spend up to six months in prison.

The three-time Pro Bowl player was charged with lying about his
alleged use of performance-enhancing drugs when he testified before
the BALCO grand jury in 2003.

The charges were unsealed today in federal court in San Francisco.

The government contended that the 37-year-old Stubblefield made false statements to an IRS agent when he allegedly said he had not used steroids linked to the Bay Area Laboratory Co-Operative and denied receiving performance-enhancing drugs from BALCO founder Victor Conte.

Stubblefield played for KU in the early 90's before spending most of his NFL career with the San Francisco 49'ers.
