COLUMBIA, Mo. (AP) -- Freshman quarterback Chase Daniel led

Missouri to two fourth-quarter scores, and Adam Crossett's 26-yard

field goal in overtime gave the Tigers a 27-24 win over Iowa State

on Saturday.

Iowa State had the ball first in overtime, and Bret Culbertson

was wide right on a 43-yard field goal attempt. Missouri then took

possession on the 25-yard line, and Daniel completed an 8-yard pass

and ran three times to set up Crossett's game-winner.

The Tigers (4-2, 2-1 Big 12) also beat Iowa State (3-3, 0-3) in

overtime a year ago.

Missouri's rally came without its best player, quarterback Brad

Smith, the school's all-time leader in both rushing and passing.

With the Tigers down 24-14 and facing second-and-10 at their 25

with just under nine minutes left, Smith was hit in the head on a

tackle by Iowa State linebacker Tim Dobbins.

Smith was down for a couple of minutes before slowly walking off

on his own with a teammate's arm around him. His availability for

next week's game against Nebraska was not immediately known.

Enter Daniel, a highly regarded recruit from Texas whom coach

Gary Pinkel has played for at least one series each game.

Taking over on third-and-10, Daniel completed five passes for 63

yards -- including one on fourth-and-7. Crossett's 19-yard field

goal made it 24-17 with 4:44 to play.

Missouri got the ball back with 2:32 left, and Daniel led an

87-yard drive, completing six passes for 75 yards, including a

4-yard touchdown pass to Sean Coffey with 20 seconds to play.

Missouri's defense scored twice during a three-play sequence in

the first quarter to put the Tigers ahead 14-0.

Safety William Moore stepped in front of a short pass by Bret

Meyer and returned it 62 yards for a touchdown with 7:10 to play in

the quarter.

Two plays and 44 seconds later, Iowa State's Jason Harris

fumbled on a hit by Jamar Smith, and Xzavie Jackson picked up the

ball and ran 16 yards for a touchdown.

Then Iowa State took over, scoring 24 straight points while

flustering Smith, who had one of the worst games of his career. He

rushed for 39 yards on 11 carries and completed just eight passes

for just 45 yards. He also threw an interception and fumbled.

Iowa State made it 14-7 early in the second quarter on Ryan

Kock's 1-yard-run on fourth-and-goal. It was the first of three

1-yard scores for Kock.

The Cyclones then used 9:15 off the clock but had to settle for

Culbertson's 42-yard field goal with 31 seconds left in the half.

On the last play of third quarter, Smith's pass over the middle

was intercepted by Nik Moser and returned 19 yards to the Missouri

10. Three plays later, Kock scored his second touchdown.

Brad Ekwerekwu's fumble on a reverse at the Missouri 36 early in

the fourth quarter gave the Cyclones good field position, setting

up Kock's third touchdown.

Meyer was 16-25 for 169 yards and an interception for the

Cyclones. Greg Coleman carried 25 times for 104 yards.
