The 35-year-old Reed was released Tuesday by Houston, cleared waivers Wednesday and joined the Jets a day later. He was at the team's facility Thursday and expected to practice with his new Jets teammates.
Ryan coached Reed for several years in Baltimore. He acknowledged Wednesday that he and general manager John Idzik discussed the possibility of adding him.
Reed missed the Texans' first two games after hip surgery and was recently relegated to a backup role, making just 16 tackles. He was unhappy about not starting and criticized the team for being outplayed and outcoached after the Texans' seventh straight loss last Sunday.
