Jenny Vrentas of the Newark Star Ledger broke the news that the Giants have brought back the outside linebacker to a one-year deal.
The money involved in the contract was not disclosed as of yet.
Rivera was acquired by the Giants in April 2012 for a fifth-round pick in the 2012 NFL draft.
The 26-year-old former first-round pick back in 2008 had fell out of favor with the Cincinnati Bengals due to injuries and the Giants were able to acquire him for very cheap.
In 2012, Rivers played in 11 games—starting in just six of them—and had 38 total tackles.
With the release of Michael Boley at outside linebacker and the possibility that Mathias Kiwanuka is moving back to defensive end, Rivers will likely get a chance to become a starter this year.
When Rivers was healthy and on the field, he showed glimpses of why he was a former first round pick, but injuries have been his down fall in the NFL.
But with the lack of depth at the outside linebacker position, bringing back Rivers made sense.
Now, if he can only stay healthy, he has a legit chance to be the every-game starter and attempt to live up to the potential that he had when coming out of USC.
I've always been very high on Rivers and think this is a good move for the team and hope he can stay healthy enough on the field in 2013 to contribute and make a difference.
