The Titans designated Haynesworth as their franchise player Feb. 20, but he is not under contract. The only way Haynesworth can take part would be to sign the tender worth approximately $7.8 million, which would be 120 percent of his salary for 2007.
The 14-week program starting Monday is voluntary.
"Albert has not signed his tender and therefore will not be participating in the Titans offseason program at this time," agent Chad Speck wrote in an e-mail Monday.
Speck said Haynesworth is working out on his own and will be ready for the 2008 season.
