NEW YORK - New York Giants wide receiver Brandon Collins was suspended without pay for the first four games of the regular season for violating the NFL Policy and Program for Substances of Abuse.

The NFL announced the suspension of the first-year player on Monday. Collins signed with the Giants as an undrafted free agent.

The 24-year-old Collins will be eligible to return to the Giants' active roster on Sept. 30, the day after the team plays the Kansas City Chiefs. The Southeastern Louisiana product spent part of last season on the Giants' practice squad and will be eligible to participate in all offseason and preseason practices and games.

Collins had played well in the recent veterans minicamp.

Also, fullback Vonta Leach said the Giants have expressed an interest in him.

During an interview Monday with SiriusXM NFL Radio, Leach said the Giants called his agents the day he was released by the Super Bowl-champion Baltimore Ravens.

The Giants' plans at fullback took a hit when Henry Hynoski suffered a knee injury during the spring and needed surgery.

Leach, who failed to reach terms on a restructured contract with Baltimore, earned Pro Bowl honors the past two seasons with the Ravens. He had 21 carries for 67 yards and a touchdown. He also had 36 catches for 212 yards.

The 31-year-old has played with the Packers, Saints and Texans.

"Everything is picking up here a little more," Leach said. "We'll see how this week goes."
