BALTIMORE _ Ravens quarterback Lamar Jackson was one of several players who returned to practice Thursday.
Coach John Harbaugh said Monday that multiple players, including Jackson, were battling the flu.
Five Ravens were not seen at the open portion of practice Thursday: running back Mark Ingram II, rookie wide receiver Marquise "Hollywood" Brown, tight end Hayden Hurst, guard Ben Powers and defensive back Brandon Carr.
In a week in which the team won't find out its opponent for the divisional round until Saturday, cornerback Marlon Humphrey said a "chippy" practice helped keep the team focused.
"We had a very vocal practice today, a little bit of chirping back and forth today, so it was really fun," Humphrey said with a grin. "I can't get into too many details, you know, but it was a good practice, really fun.
"Sometimes to get yourself going, you just got to talk a little trash at the offense. ... Lamar's been kind of sick. He threw an incompletion, I was like, 'Where's the Pepto-Bismol?' It was a lot of chirping like that, and it was fun."
