Delanie Walker and Ryan Succop have become the latest veterans to be released by the Tennessee Titans ahead of free agency.
The Titans confirmed the roster moves on Friday, a day after pass rusher Cameron Wake and running back Dion Lewis were also cut ahead of a key offseason for the team.
After reaching the AFC Championship game, big decisions need to be made on free agent quarterback Ryan Tannehill and running back Derrick Henry, with the franchise and transition tags at their disposal.
The Titans have also been linked with a pursuit of New England Patriots QB Tom Brady when free agency begins on March 18.
Tight end Walker spent seven years with the Titans, racking up 5,888 yards and 36 touchdowns in making three Pro Bowls, but an ankle injury restricted him to just eight games over the past two seasons and he was released with a failed physical designation.
"In my time here with Delanie, he has been an absolute pro on the field, in the locker room, and his production speaks for itself," Titans general manager Jon Robinson said.
"He was a leader, a captain, and a highly respected member of this team. His toughness, competitiveness, attitude and professionalism are what we expect from our players. I want to wish him all of the best moving forward and he will forever be a Titan great.
"Over the last two days I have had the difficult task of informing a number of our players they are being released.
"These aren't easy conversations, but I want to thank each of them for the significant contributions they have made to our organisation."
The Minnesota Vikings made moves as they released cornerback Xavier Rhodes and defensive tackle Linval Joseph, while vowing to "remain in communication" with both players during free agency with a view to re-signing them.
"Both Linval and Xavier have personified what it means to be a Minnesota Viking since joining our organisation, providing incredible leadership on the field, in the locker room and within the community," said GM Rick Spielman.
Tackle Cordy Glenn was released by the Cincinnati Bengals, saving the team $9.5million in cap space.
