Details about the contract are not immediately known; it's expected to be announced Wednesday when the new league year begins.
Irvin, a first-round pick by the Seahawks in 2012, helped the team win back-to-back NFC championships, and Super Bowl XLVIII.
Irvin also found ways to make headlines for negative reasons; he was suspended in 2013 for violating the NFL’s substance abuse policy, and made history by becoming the first player to be ejected in a Super Bowl.
