Hamilton, the 11-year veteran who has played 158 games for the Giants, ruptured his right Achilles' tendon in Sunday's 17-10 loss to the Atlanta Falcons. He will undergo surgery later this week and faces a six-month rehab.
Frisch, a 6-5, 267-pounder, will provide depth on the defensive line where, in addition to Hamilton, Kenny Holmes missed the Atlanta game with an elbow injury and Michael Strahan suffered back spasms and played only on third downs in the second half.
Frisch was a third-round draft choice of the Tennessee Titans in 2000 (the 93rd choice overall) after an outstanding career at BYU. He was inactive for all 16 games in the 2000 season and was released by the Titans on Sept. 2, 2001.
Dallas signed Frisch on Sept. 24, 2001. He saw his first NFL action against Oakland on Oct. 7. Frisch got his first tackle against Washington a week later. He picked up his first sack when he brought down Kerry Collins for an 8-yard loss on Nov. 4 in Giants Stadium. Frisch forced Collins to fumble on the play, and the ball was recovered by Brandon Noble, setting up a Dallas touchdown.
Frisch finished the season with eight tackles and three sacks for 31 yards in losses.
Frisch was a four-year starter at BYU, where he totaled 222 tackles, 25 sacks, seven forced fumbles and four fumble recoveries. Frisch was a star player at Vista High School in Bonita, Calif. He was born on Dec. 17. 1976.
