Landry has been suspended for 10 games by the NFL for violating the performance-enhancing drug policy.
Landry, who was released by Indianapolis on Feb. 11, missed the first four games of 2014 with a previous league suspension for the same reason. He also was on the commissioner's exempt list for one game last season. The 30-year-old Landry joined the Colts as a free agent in 2013, getting a $24 million, four-year contract. He also has played for Washington for his first five pro seasons, and spent one season with the New York Jets.
