A Georgia college student said she felt powerless to stop a short-tempered Ben Roethlisberger from having sex with her in a bar bathroom even though she told him to stop, telling investigators: "I'm a little girl and he's a big boy."

Her interviews with police were among more than 50 audio and video clips released yesterday from the investigation into Roethlisberger's late-night carousing in a Milledgeville, Ga., a sordid incident that didn't result in criminal charges but reinforced his reputation for petulant behavior.

The DVDs offered the first extensive account by the accuser, who hasn't spoken publicly, as well as less than a minute of shaky Roethlisberger footage from the club. With loud music blaring, the Pittsburgh Steelers star asks a girl what her drink tastes like, doles out high-fives, strikes a pose, punches his fist in the air twice and flashes a huge grin for the camera.

Before the night was done, he was accused of sexually assaulting a 20-year-old woman, who said she didn't try to fight him off because he appeared to anger easily.

"I noticed throughout the night he kind of had like a short temper, like he would get really, like, defensive," she told investigators, but didn't elaborate on what made her think the quarterback had a short temper.

The local prosecutor determined there wasn't enough evidence to warrant criminal charges after the investigation into the March 5 incident concluded, and he said the woman ultimately asked him not to prosecute the quarterback.

Noteworthy

* The NFL Players Association filed a complaint alleging the league deprived players of potential revenue when it renegotiated its contracts with television networks. The complaint says the league structured the contracts so it would be guaranteed money even if there is a lockout in 2011 while not maximizing revenue from the previous two seasons - when the NFL would have to share that income with players. The current collective bargaining agreement expires in March, which could lead to a work stoppage during the 2011 season. In a statement, the NFL noted that union executive director DeMaurice Smith had praised the deal earlier this year.

* Miami wide receiver Brandon Marshall, acquired in a trade with Denver in April, said his surgically repaired hip has improved enough to allow him to participate in individual drills. He isn't expected to take part in team workouts until training camp.

* Green Bay cornerback Brandon Underwood is facing sexual assault claims made by two women following a weekend incident in Lake Delton, Wis. His attorney, Richard Kaiser said Underwood is the target of the investigation. Police cleared six of seven Packers players of wrongdoing but have not revealed the identity of the seventh player. Police have said they do not plan to recommend pressing charges because of inconsistencies in the women's statements. Underwood has apologized to teammates for creating a distraction.

* Carolina weakside linebacker Thomas Davis suffered a torn anterior cruciate ligament in his right knee for the second time in 7 months, likely leaving the Panthers without him for the 2010 season. Davis' knee buckled in a noncontact drill in a voluntary workout on Tuesday.

* New Orleans made one long-term contract offer to Pierre Thomas since the Super Bowl, and the value was not close to what the club's leading running back was seeking, Thomas' agent, Lamont Smith, said. The Saints did not comment. Thomas, who signed a 3-year contract with the Saints as an undrafted rookie in 2007, is a restricted free agent. Smith said the Saints tendered Thomas a 1-year offer of about $1.7 million, but would not negotiate.

* St. Louis wide receiver Isaac Bruce, whose four Pro Bowls firmly established him among the greatest players in team history, retired. The 37-year-old Bruce is stepping away after 16 seasons in which he set virtually every franchise receiving record. He's second in the NFL in career receiving yards with 15,208, tied for second in yards per catch (14.9), fifth in catches (1,024) and ninth in receiving touchdowns (91).
