Lyon (lower body) pronounced himself healthy and will be ready to play whenever he is called upon, Paul Hamilton of WGR Sports Radio 550 reports Saturday.
Lyon last played April 4 in Washington, allowing three goals on five shots before being pulled. He was injured at practice April 8 and was unable to play the remainder of the regular season. He ended the campaign with a 20-10-4 record, a 2.77 GAA and a .906 save percentage across 36 regular-season contests. Ukko-Pekka Luukkonen is expected to start Game 1 versus Boston on Sunday, but Lyon will be available if needed.
