A filly is going to challenge the boys in the Preakness for the first time since 2009 when Rachel Alexandra won.

Ria Antonia will be ridden by Calvin Borel, who guided Rachel Alexandra to victory. Ria Antonia is coming off a sixth-place finish in the Kentucky Oaks on May 2 at Churchill Downs, where she has been training.

For the first time in the Preakness, a filly, a female jockey and a female trainer will all compete at the same time. Rosie Napravnik will ride Bayern, and trainer Linda Rice will saddle Kid Cruz. The 139th Preakness is Saturday in Baltimore.

College

The NCAA's next big challenge could come from federal lawmakers.

A U.S. senate committee sent a letter to NCAA President Mark Emmert urging the governing body and college and university leaders to provide athletes with greater protection from potential "exploitation" on college campuses. The letter, obtained by The Associated Press on Monday, called on Emmert and member schools to act.

The letter was signed by three members of the Committee on Commerce, Science and Transportation: West Virginia Sen. Jay Rockefeller, the chairman; Missouri Sen. Claire McCaskill, the chairwoman of the subcommittee on consumer protection, product safety and insurance; and New Jersey Sen. Cory Booker. All three are Democrats.

The NCAA has not yet commented on the letter.

  • Former Minnesota quarterback Philip Nelson was charged with two counts of felony assault after a weekend fight outside a Mankato bar that left another man gravely injured.

    NFL

    Linebacker Darius Fleming, after two career-changing knee injuries, was released along with wideout DeMarco Sampson and cornerback Dax Swanson to make room for the 49ers' incoming class of undrafted free agents. Six signings became official Monday: linebacker Shayne Skov (Stanford), outside linebacker Morgan Breslin (USC), quarterback Kory Faulkner (Southern Illinois), center Dillon Farrell (New Mexico), offensive tackle Fou Fonoti (Michigan State) and tight end Asante Cleveland (Miami).

  • Cleveland released veteran quarterback Vince Young a few days after drafting Johnny Manziel. Young, signed on May 1, hasn't played in an NFL regular-season NFL game since 2011.

  • Cincinnati released backup quarterback Josh Johnson, two days after it took Alabama quarterback A.J. McCarron in the fifth round of the draft. The team also signed 10 undrafted college free agents, including tight end/fullback Ryan Hewitt from Stanford.

  • St. Louis wide receiver Stedman Bailey has been suspended without pay for the first four games of the season for violating the NFL policy on performance enhancing substances.

  • Green Bay released former Stanford linebacker Chase Thomas.

  • Jacksonville signed defensive lineman DeAndre Coleman, an undrafted free agent from Cal.

    Soccer

    The cost of building Brasilia's World Cup stadium has nearly tripled to $900 million in public funds, largely because of allegedly fraudulent billing, government auditors say. An Associated Press analysis of data from Brazil's top electoral court shows skyrocketing campaign contributions by the very companies involved in the most Cup projects.

  • Major League Soccer and U.S. Soccer have signed new broadcast rights deals with ESPN, Fox and Univision. The new deals are for eight years through 2022.

    Hockey

    Viktor Tikhonov scored twice and Alex Ovechkin added a goal and two assists as Russia routed the United States 6-1 in Minsk, Belarus, for its third straight victory at the ice hockey world championships. In the day's other big matchup, Canada downed the Czech Republic 4-3.
