He is out indefinitely.
Amukamara, the Giants' first-round selection in the 2011 NFL draft, left midway through Saturday night's practice with a member of the Giants' medical staff, and X-rays revealed the fracture, which will require a procedure in which a screw will be inserted into his left foot. It was just Amukamara's second practice with the team after becoming the last first-rounder to sign a contract. He practiced with the team for the first time on Friday night.
Amukamara wound up missing the team's first five practices while his agent worked out the details of a four-year, $8.1 million deal, with the first three years fully guaranteed and a little more than half of the fourth year guaranteed.
The Giants had hoped that the 19th overall pick out of Nebraska would proved them with depth at the cornerback position behind starters Corey Webster and Terrell Thomas, and reserve Aaron Ross. The Giants are now extremely thin at cornerback, having already lost reserve Bruce Johnson, who was waived after he ruptured his Achilles tendon Thursday.
Left tackle William Beatty broke the fifth metatarsal in his right foot last season in the regular-season opener against the Carolina Panthers. He missed two months (six games), but did not go on the injured reserve list.
The Giants also announced that tight end Ben Patrick "no longer wants to play football" and has been placed on the reserve/retired list.
Patrick played four seasons in the NFL -- all with the Cardinals -- compiling 446 yards and four touchdowns on 45 receptions in 42 games.
