Former 49ers defensive lineman Dana Stubblefield is behind bars.

According to the Mercury News, Stubblefield was led away from court to jail in handcuffs Friday after a judge found there was probable cause to hold him over for trial on charges of rape stemming from May 2015.

Stubblefield is charged with raping an intellectually disabled woman on April 9, 2015 at his Morgan Hill home when she had gone to interview for a babysitting job.

According to the same report, Stubblefield had been free on $250,000 bail for more than a year. But the judge ordered him taken into custody Friday after prosecutors formally added the allegation that Stubblefield used a gun during the assault, which made it a no-bail case.

Stubblefield has pleaded not guilty and publicly denied the five felony charges and gun enhancement that prosecutors say could lead to at least 15 years to life in prison if he is convicted.

Stubblefield played 11 seasons in the NFL, including the first five with the 49ers. He later returned to the 49ers in 2001 and ’02, before finishing his career with the Raiders.

Stubblefield, a first-round pick of the 49ers in 1993, was the NFL Defensive Rookie of the Year after recording 10.5 sacks. He was named the NFL’s Defensive Player of the Year with a career-high 15 sacks in 1997. He signed a lucrative contract with Washington in 1998.
