Mike Sullivan reports to work every morning when the Penguins are scheduled to practice with a plan for that day's workout.
He just never knows who's going to be around to execute it.
Not until the latest round of COVID-19 test results comes in, anyway.
"We go into the day with a specific game plan," Sullivan said after practice Friday. "And sometimes lately, it seems like we're thrown curveballs when we get in in the morning, and we've got to make adjustments accordingly."
Friday, that meant getting versatile forward Evan Rodrigues back from the NHL's Covid protocol, but having center Jeff Carter enter it for the second time in a little over two months.
