Allen, 23, has dressed in 23 games for Chicago this season, ranking fourth among all AHL goalies with 14 wins (14-7-2) while his 2.17 GAA ranks third and his .922 SV% is 10th best. His demotion to the AHL means that Jaroslav Halak is back to full health and will suit up on Tuesday, whether as the start or the back-up.
