A person familiar with the decision says Garrard plans to retire because of lingering knee issues, leaving the Jets one fewer quarterback in their open competition.

David Garrard says his surgically repaired left knee kept swelling up on him after workouts, and that forced him to realize he couldn't compete for the New York Jets' starting quarterback job.

Garrard tells SiriusXM NFL Radio on Thursday that his decision to consider retirement was a result of his knee not being healthy, not because the Jets drafted Geno Smith in the second round.

Garrard says his knee was "never just allowing me to just go on and just play without worries." The Jets signed him in March, and he was expected to compete with Smith, Mark Sanchez and the team's other quarterbacks for the starting job.

Garrard adds that the Jets offered him "a little bit of an internship" to work with the team's quarterbacks during training camp.
