Kallgren will tend the twine versus Buffalo at home Tuesday, Terry Koshan of The Toronto Sun reports.

EDGE Analysis

Kallgren will take Tuesday's game in order to give starter Jack Campbell some extra rest. In his nine outings, the 25-year-old netminder is 5-2-1 with a 2.78 GAA and one shutout. With an upcoming back-to-back as well, Kallgren will likely be in the crease versus the Senators or Islanders on Saturday or Sunday, respectively.
