SAN DIEGO -

Shannon Eastin became the first woman to officiate an NFL game and the San Diego Chargers slogged to a sloppy 21-13 preseason victory over the Green Bay Packers.

Eastin broke the NFL's on-field gender barrier by serving as the line judge for the seven-man crew of replacement officials.

She helped oversee a predictably ugly preseason opener by both teams, filled with fumbles, interceptions and missed assignments.

Philip Rivers had a touchdown, an interception and a fumble in limited action for the Chargers ( No. 16 in the AP Pro32). Rookie Jarrett Lee got most of the action, throwing for 235 yards and a touchdown.

Aaron Rodgers had an interception and a fumble in three series for the Packers (No. 1).
