Allen will be in the cage for Sunday's game against the Red Wings, Jeremy Rutherford of the St. Louis Post-Dispatch reports. Allen was due to get a start for one half of the Blues' weekend back-to-back set, and coach Ken Hitchcock decided to save the netminder for Detroit due to Brian Elliott's strong career numbers against the Wild. After rough showings his previous two turns, Allen appeared to get back on track his last time out Mar. 15 against the Stars, denying all 28 shots he faced to claim his fourth shutout of the season.
