Roslovic entered the NHL's COVID-19 protocols Sunday, Blue Jackets team reporter Jeff Svoboda reports.
Roslovic will need to submit two negative COVID-19 tests before rejoining the Blue Jackets, so he'll miss Monday's matchup with the Sabres at a minimum. Fellow center Boone Jenner also entered the NHL's COVID-19 protocols Sunday, so look for Emil Bemstrom and Gregory Hofmann to enter the lineup against Buffalo.
