Prince Amukamara’s NFL debut will be delayed a while.

The Giants’ first-round draft choice – who reported to training camp on Friday – suffered a fracture of the fifth metatarsal bone in his left foot on Saturday.

The rookie cornerback from Nebraska will need surgery, the team announced.  He is out indefinitely.

Amukamara, who was drafted by the Giants with the 19th overall pick, was participating in his second practice. He left the field with a member of the Giants medical staff and X-rays subsequently revealed the fracture - which will require a procedure in which a screw will be inserted into his left foot.

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.

It’s the second big injury the Giants have suffered at cornerback in this camp. On Thursday, Bruce Johnson ruptured his Achilles tendon. He will undergo surgery and is out for the season.

The Giants still have three experienced corners in starters Terrell Thomas and Corey Webster, plus fifth-year pro Aaron Ross. But until Amukamara returns, additional depth must come from a pool of largely untested players, including Michael Coe, Brian Witherspoon and Joe Burnett.
