In brief: Players show their support for labor union

With their index fingers in the air, players at half of the 12 NFL afternoon games Sunday, including four-time MVP Peyton Manning, showed their solidarity in support of the union in collective bargaining negotiations.

At Houston, Jacksonville, Tampa, St. Louis, Seattle and Orchard Park, N.Y., players held up their index fingers before kickoff, replicating the gestures made by the Saints and Vikings before Thursday night’s season opener in New Orleans.

The demonstrations are designed to show the support players have for each other in the final year of the CBA, from which the owners opted out in 2008.

The NFL is looking into how a female television reporter was treated at New York Jets practice Saturday.

Ines Sainz, a reporter for Mexico’s TV Azteca doing a story on quarterback Mark Sanchez, had footballs thrown in her direction by a Jets coach during practice, and players later called out to her in the team’s locker room.

NFL spokesman Greg Aiello said that the league and the Jets began looking into the situation when they were made aware of it Saturday night.

• The NFL is investigating a complaint by an unidentified team that the New York Jets violated the league’s offseason training rules during a camp organized by Sanchez because coaches were present for some workouts.

ESPN.com first reported that the unidentified team claims Sanchez’s “Jets West Camp” in Southern California in July violated rules when coach Rex Ryan and offensive coordinator Brian Schottenheimer watched some sessions.

The Jets could be subject to a warning, fine, forfeiture of a draft pick or loss of organized team practices.
