The team said Friday that both tested positive for the virus and will remain in isolation. Forward Brandon Sutter tested negative. All three players missed Pittsburgh's two-game road swing through Florida after coming down with symptoms suggesting mumps.
Penguins captain Sidney Crosby, forward Beau Bennett and defencemen Olli Maatta had previously been diagnosed with the virus that has hit several NHL teams. Crosby missed a week but has returned to play. Bennett and Maatta remain out with unrelated injuries.
Sutter could be available Saturday when the Penguins host Washington.
