Hightower, 30, has made one of the NFL's most remarkable comebacks during the past two years with the Saints after spending three-plus years out of the league because of a knee injury.
Hightower tweeted thanks to the Saints for giving him a chance "when no one else would."

Hightower, who began his career with the Cardinals, suffered a torn ACL after being traded to the Redskins in 2011. Doctors later discovered an infection that was stunting his recovery.
The 6-foot, 220-pounder has combined for 923 rushing yards, 329 receiving yards and nine touchdowns in the past two years as a backup to Mark Ingram. And he has shown the ability to take over as an every-down back when needed, with a pair of 100-yard rushing games.
Hightower has a total of 2,977 rushing yards, 1,208 receiving yards and 34 touchdowns in six seasons.
