Dolphins release veteran quarterback David Garrard
Garrard signed in March and climbed atop the depth chart in training camp before he was sidelined by a left knee injury that required arthroscopic surgery Aug. 11. In his absence, Tannehill claimed the starting job for Sunday's opener at Houston.
The 34-year-old Garrard's $2.25 million salary would have been guaranteed if he was on the roster for the opener. He returned to practice Monday on a limited basis and said he's not yet 100 percent.
