With McCourty due a base salary of $7 million in the final year of his deal, the Titans decided to move on. The team's offseason program begins Monday; the timing of the move means McCourty, a respected veteran, won't be asked to show up, only to be cut later.
Even if McCourty had taken a reduced deal and stayed, the Titans still would have been active at cornerback in the upcoming NFL draft, where they have the fifth and 18th picks in the first round.
The team signed Logan Ryan from New England in free agency and has significant room to improve the NFL's 30th-ranked pass defense.
McCourty, 29, played in 108 games with 90 starts and 13 interceptions for the Titans, forcing six fumbles and recovering five, two of which he turned into touchdowns. He signed a six-year, $43 million extension with $20 million guaranteed on Aug. 23, 2012.
McCourty's twin brother, Devin, plays for the Super Bowl champion Patriots.
