The Baltimore Ravens are bullish that quarterback Lamar Jackson missing practice due to a non-COVID-related illness this week is not a "big deal" ahead of Sunday's game against the Chicago Bears.

Jackson was not part of Thursday practice due to illness, having been sent home from the team facility on Wednesday morning.

Ravens head coach John Harbaugh clarified the illness was not COVID-related, easing doubts about Jackson's availability for Sunday's game, but Thursday's practice was the fourth time he has missed a session this season.

"I don't really think it's that big of a deal," Ravens center Bradley Bozeman said on Jackson's absences. "I know Lamar is doing his things at home that he needs to do. He's watching plays. He's getting everything right at home.

"When he comes back in, he's not going to miss a step. Week in and week out, he's continued to build on that and step up to the plate when he needs to. I don't see that being an issue."

The Ravens quarterback is enjoyed an MVP-like season, ranking eighth in the NFL in passing (2,447 yards) with 14 touchdowns and seventh in rushing (639 yards) with two touchdowns.

Ravens offensive coordinator Greg Roman added: "I think he's feeling better."
