NFL rushing leader DeMarco Murray suffered a broken left hand that requires surgery and may miss Sunday's game against Indianapolis as the Dallas Cowboys make a run at a playoff berth.

Cowboys executive vice president Stephen Jones said on his radio show that Murray was scheduled to have surgery Monday. Murray suffered the injury against the Eagles on Sunday night.

Murray has 1,687 yards rushing and needs 87 yards to break all-time NFL rushing leader Emmitt Smith's franchise record of 1,773 yards.

Johnny flop

Along with being sacked, taunted, embarrassed and generally mistreated on Sunday by the Cincinnati Bengals, Johnny Manziel got humbled.

The Browns rookie quarterback said Monday that his first NFL start, a 30-0 loss that essentially eliminated Cleveland from the playoffs, was the toughest day he's ever had on a football field.

"It's the first game I've ever not scored a point in and been shut out," Manziel said.

Union, Peterson sue

The NFL Players Association filed a federal lawsuit for Adrian Peterson, asking the court to dismiss an arbitration ruling that upheld the NFL's suspension of the star running back.

The petition also requested a court order for Peterson's immediate reinstatement, arguing that Peterson has served far more than what's allowed by the collective bargaining agreement between the league and the players. Attorneys for the NFLPA asked to expedite the case in Minnesota, where the union has often gone to contest labor matters with the NFL.

Cards' Lindley to start

Five weeks removed from the San Diego practice squad, Ryan Lindley will start at quarterback for the Arizona Cardinals against Seattle on Sunday night.

Coach Bruce Arians announced the decision following the team's practice, with experience the deciding factor in choosing Lindley over rookie Logan Thomas in what figures to be the biggest game for the Cardinals this season.
