— NFL on CBS 🏈 (@NFLonCBS) September 28, 2025With how the game was going, the Ravens were probably getting close to the point where they were going to have to consider taking Jackson out anyway. But they obviously weren’t going to take any chances with Jackson dealing with a hamstring injury and the team trailing by 17 points late in the third quarter. The Kansas City defense sacked Jackson three times, picked him off once and held him to 147 yards passing. Jackson also lost a fumble in the first half.The Ravens, who won the AFC North last season, dropped to 1-3. Since 1990, only 35 teams have reached the playoffs after starting 1-3. This couldn’t have been a worse afternoon for the Ravens.
