EAST RUTHERFORD, N.J. (AP) New York Giants starting safety Bennett Jackson suffered a major knee injury against the Jacksonville Jaguars and will be lost for the season, the latest injury that has ravaged the team's most inexperienced position.

Free-agent safety Justin Currie broke his right ankle earlier in the game Saturday night covering a kickoff, and Jackson went down in the waning minutes of the 22-12 victory, playing because the team didn't have enough safeties.

Rookie Mykkele Thompson was lost last week when he sustained an Achilles tendon injury in the preseason game against Cincinnati. Second-round draft pick Landon Collins sprained a knee in that game, and Cooper Taylor (toe) and Nat Berhe (calf) were out with injuries sustained in practice.

Coach Tom Coughlin hopes Collins, Taylor and Berhe can return this week.

Coughlin didn't know how long starting middle linebacker Jon Beason will be out with a sprained left knee. Jameel McClain will move into his spot.
