Osi Umenyiora is expected to sign a contract with the Giants -- just not the kind of contract that puts him back on the field to help the team's pass rush.

The former Giants sack specialist, who helped the team win the Super Bowl after the 2007 and 2011 seasons, will sign a one-day contract to retire as a Giant, according to a source familiar with the situation. The move is expected to happen during training camp, which begins Friday.

The contract would not preclude Umenyiora from returning to the NFL if he wants to resume playing for another club.

Umenyiora, 33, joined the Giants as a second-round draft pick out of Troy State in 2003 and played 10 seasons before signing with the Falcons in 2013 as a free agent. He had 75 sacks for the Giants and 10 more for the Falcons.

Umenyiora was a first-team All-Pro in 2005, when he had a career-high 14 1/2 sacks. He was a second-team All-Pro in 2010. He had 13 sacks in the Giants' 2007 championship season and nine in 2011, when the Giants beat the Patriots in the Super Bowl for the second time.

The Giants face an uncertain situation at defensive end after Jason Pierre-Paul was hurt in a fireworks accident July 4. Pierre-Paul reportedly had the index finger on his right hand amputated and suffered fractures in his right thumb.

Umenyiora had been mentioned as a potential short-term replacement for Pierre-Paul, but the contract he's expected to sign is purely ceremonial.
