PITTSBURGH -- Mason Rudolph has been here before.
A week of preparation as the Pittsburgh Steelers' starting quarterback without his status as starter set in stone.
Quarterback Ben Roethlisberger, who tested positive for COVID-19 on Saturday, needs to be symptom-free for 48 hours and two negative tests taken 24 hours apart to exit the league's COVID-19 protocol.
Until then, Rudolph is preparing as if he will start Sunday night against the Los Angeles Chargers.
"It's just the nature of being a backup quarterback right now," he said Thursday.
