New York Giants rookie running back Wayne Gallman is set to play a significantly larger role in Week 5 now that incumbent starter Paul Perkins has been ruled out versus the Los Angeles Chargers due to a rib injury.

Gallman got his first taste of NFL playing time in the Giants' 25-23 loss to the Tampa Bay Buccaneers last weekend. With Perkins plodding away at an average of 1.9 yards per carry this season, Gallman received 11 rushing attempts and gained 42 yards for an average of 3.8. He added 8 yards on two receptions.

The Giants' active backfield for their fifth game of the season will be made up of Shane Vereen, Orleans Darkwa, and Gallman. Vereen will handle the majority of the passing-down work, but with just 12 rushing attempts on the season he shouldn't be much of a roadblock for Gallman. Darkwa has carried the ball just 13 times through three games.

Gallman was a top waiver-wire addition coming out of his Week 4 debut, but he remains available in the vast majority of Yahoo! leagues. He's worth adding in all formats, while the projected starting role makes him worthy of RB2/FLEX consideration in standard scoring. Owners in PPR formats can keep him on the bench until he's able to create some separation from Vereen, who still played 28 percent of the offensive snaps in Week 4, according to Football Outsiders.

Meanwhile, it's well past the time to drop Perkins in all formats.
