Nurse was designated for the NHL's COVID-19 protocols Monday.
Edmonton was already off until Dec. 27 against the Flames, so it's possible Nurse will avoid missing any games. In his last six contests, the 26-year-old blueliner has managed just one helper while also recording 28 shots, 15 hits and 10 blocks. If Nurse is sidelined versus Calgary, the Oilers will need to call up a defenseman or two from the minors.
