(CHICAGO) – Chicago Blackhawks goaltender Corey Crawford practiced Saturday after he missed the start of training camp following a positive COVID-19 test. Crawford, 35, said he was in quarantine at his place in Chicago. Crawford's return is a big development for Chicago as it prepares for its qualifying series against the Edmonton Oilers and their high scoring duo of Connor McDavid and Leon Draisaitl. But he has little time to get up to speed before Game 1 of their best-of-five series on Aug. 1. Crawford missed parts of the previous two seasons because of concussions. He had been playing well when the league was shut down, recording a .930 save percentage in his last 17 games. Crawford was in net when Chicago won the Stanley Cup in 2013 and 2015. He is 48-37 with a .919 save percentage and 2.28 goals-against average in 87 career playoff appearances.
