Allen will be in net for the Blues on Thursday against the Ducks, Jeremy Rutherford of the St. Louis Post-Dispatch reports. Allen has been a decent backup for Brian Elliot so far this season, appearing in two games, posting a 1-1-0 record and a .915 save percentage. The Blues may just be giving Elliot a day off so expect Allen to continue to be the backup for at least the near future.
