Lyon (lower body) will not be an option for Game 1 of the postseason, Mike Harrington of The Buffalo News reports Wednesday.
Lyon is reportedly on track to return at some point during the first-round series, though head coach Lindy Ruff didn't offer a specific recovery timeline. Once Lyon receives the all-clear, he will likely face an uphill battle to unseat Ukko-Pekka Luukkonen as Buffalo's starter.
