ATLANTA -- Michael Vick's legal troubles prompted Nike on Thursday to suspend the release of its latest product line named after the Atlanta Falcons quarterback.

Nike has told retailers it will not release a fifth signature shoe, the Air Zoom Vick V, this summer. Nike spokesman Dean Stoyer said the four shoe products and three shirts that currently bear Vick's name will remain in stores. Vick will be arraigned next week in a Richmond, Va., federal courtroom on charges of sponsoring a dogfighting operation.

Stoyer said the company still has a standing contract with Vick but declined to speculate on his future with Nike.
