The Kansas City Chiefs lead the Baltimore Ravens, 24-14, at halftime from M&T Bank Stadium in Baltimore, Md.

Quarterback Alex Smith is 12 of 15 for 91 yards passing and a touchdown.

The Chiefs began the game with the ball, and after two first downs, faced third-and-11 at their own 32-yard line. Smith scrambled on the play, but as he ran out of bounds well short of the marker, Ravens defensive lineman Timmy Jernigan hit him late, extending the drive for the Chiefs. Three plays later, running back Charcandrick West ran for a 38-yard touchdown to give the Chiefs a 7-0 lead.

The Ravens came right back on the ensuing possession when Jimmy Clausen connected with Kyle Juszczyk from 1-yard out for a touchdown.

The Ravens forced the Chiefs to go three-and-out, but on the next possession, linebacker Derrick Johnson forced RB Javorius Allen to fumble, and safety Tyvon Branch picked the ball up and returned it 73 yards for a touchdown and 14-7 Chiefs lead after one quarter.

The Chiefs added to that lead on the first play of the second quarter, when Smith found wide receiver Jeremy Maclin for a 13-yard touchdown. Maclin now leads the Chiefs with 6 touchdowns receiving on the season.

Kicker Cairo Santos added 3 points with a 53-yard field goal with less than a minute to go in the half, but before the second quarter could expire, Clausen launched a 48-yard Hail Mary pass to WR Kamar Aiken. Aiken caught the ball for a touchdown as time ran out.

The Ravens will receive the ball to start the second half.
