NFL Network Insider Ian Rapoport reported that Flacco has been dealing with "a small tear in his hip" that kept him sidelined. While the QB is approaching full health, he's not close enough to return this week.
Flacco being inactive wipes away questions about how the Ravens quarterback situation will shake out versus K.C.
The rookie has led the Ravens to a three-game winning streak. While he's struggled to move the offense through the air, the Ravens have dominated on the ground. The Ravens have amassed 200-plus rush yards in three straight games with Jackson as the team's starting QB (267 vs. Bengals in Week 11, 242 vs. Raiders in Week 12, 207 at Falcons in Week 13).
If Baltimore gets behind early, however, it will be interesting to see how much the offense opens up behind Jackson's tenderfoot passing ability.
