Lamar Jackson has tested positive for COVID-19, the second time he has done so over the past eight months.
Jackson reported to camp last Thursday and tested negative for five straight days before receiving a positive result Tuesday.
"It's just part of the deal," John Harbaugh said after Wednesday's practice. "It's just the way the world is right now."
The Ravens' player vaccination rate is at 90% and rising, according to Harbaugh.
