Baltimore advanced all the way to the Chiefs' 10-yard line with the big play coming from Ray Rice - a 37-yard run to the Kansas City 12.
The Ravens stalled after two more yards, and Justin Tucker came through for a 28-yard field goal and a 3-0 lead late in the first quarter.
The second quarter is under way with the score the same, and the Chiefs having outgained the Ravens 102-59.
Update: The Chiefs used a 13-play, 53-yard drive that swallowed 6:13 off the clock to get into field-goal range for a game-tying 30-yard kick by Ryan Succop.
So at the two-minute warning, Ravens and Chiefs are knotted at 3-3.
Oh yeah, and Jamaal Charles is in total control, already rolling up 106 yards on 18 carries for K.C.
Update II: Stat-wise, the Ravens are being dominated by the Chiefs. But where it matters, it's 3-3 at halftime.
The score is tied despite Kansas City's decided 216-106 yardage advantage, including 125 on the ground from Charles.
It's been quite a struggle for Joe Flacco and the Baltimore passing game. Flacco has completed just seven of 17 attempts for 64 yards. Rice has seven runs for 52 yards.
