East Rutherford, NJ (Betting Express) - Veteran New York Giants defensive tackle Keith Hamilton tore his right Achilles' tendon in the first quarter of Sunday's game against the Atlanta Falcons.

Minutes after Hamilton was injured, defensive end and single-season sack record holder Michael Strahan walked off the field with back spasms. His return is questionable.

Both injuries happened during a grueling touchdown drive in which Atlanta marched 88-yards in 17 plays for the game's first score. The Giants, meanwhile, were left with only four defensive lineman.

Hamilton has played all of his 11 NFL seasons with the Giants. In his career, he has recorded 62.5 sacks and 457 tackles for New York.

Strahan, who has played 10 seasons for the Giants, recorded 22.5 sacks a season ago, breaking Mark Gastineau's previous NFL record of 22.
