GLENDALE, Ariz. (Oct. 8, 2006) -- Matt Leinart 's great start wasn't good enough, and Larry Johnson 's bad day had a big but painful finish.
Leinart, in his first NFL start, completed his first six passes, two for touchdowns, against a Kansas City defense that had not allowed a scoring pass in 12 quarters to start the season.
On his second pass play, Leinart called an audible from the line of scrimmage, then lofted a 49-yard touchdown pass to Anquan Boldin.
And with the clock winding down, Leinart drove the Cardinals into field-goal range. But Neil Rackers missed a 51-yard kick that would have tied it with 2 seconds to play.
"It was fun," Leinart said. "I had a good time out there, just playing football. ... I think we can take it as a positive. I think we moved up a little bit as an offense. That was my first start. Now we can just go from there."
Johnson's big play had an ugly ending when Arizona's Antrel Rolle grabbed the star running back's facemask and twisted his head as he fell out of bounds. Johnson lay motionless for a moment before getting up and leaving on his own.
"All I remember is trying to get back on my feet and try to move around and see if everything was working," Johnson said. "I wanted to be safe about it and see if there was really something wrong or not."
Johnson planned to have an MRI on Oct. 9.
Arizona (1-4) moved from its 10 to the Chiefs 33 on its final drive, the last 26 yards on a pass to Troy Walters. But Rackers, who had connected from 41 and 45 yards earlier, was wide left.
Johnson's 36 yards were his lowest rushing total in 16 games. He also dropped a pass, missed a handoff for one fumble that was charged to quarterback Damon Huard, then fumbled the ball away again later.
"I think it was the worst production game I ever had," Johnson said.
Until that final screen pass.
"I'm a firm believer when a guy gets into a funk, you make sure he gets the ball," Chiefs coach Herm Edwards said. "Great players, you've got to give them the ball back because they're going to find a way to make a play, and he did. He made a big-time play."
Leinart, inserted in place of mistake-prone Kurt Warner, completed 22 of 35 passes for 253 yards and two touchdowns. He was intercepted once. He also saw a pass dropped in the end zone by Bryant Johnson.
"He showed good poise and I think he had a good day," Arizona coach Dennis Green said. "He did a lot of great things."
Larry Fitzgerald caught a 5-yard touchdown pass from Leinart, then left the game late in the first quarter with a hamstring injury that Green said "looked fairly serious."
Fitzgerald said he would get an MRI on Oct. 9.
"I've never had a hamstring injury or really an injury, period," he said.
Huard, starting for the third successive game in place of injured Trent Green, was 26 of 38 for 288 yards and two scores with no interceptions.
On the Chiefs' first possession, Huard and Johnson botched the handoff and Arizona's Chike Okeafor recovered at the Kansas City 41. Leinart went 4 for 4 for 37 yards, capped by a 5-yard toss to a wide-open Fitzgerald for a 14-0 edge.
The second quarter was a rough one for the rookie.
Down 20-10 after three quarters, the Chiefs went 66 yards in seven plays, Huard throwing 15 yards to Samie Parker to cut it to 20-17 with 9:35 to play. Leinart's lone big mistake followed. Ty Law picked off the rookie's pass and Tynes' 40-yard field goal tied it.
The Cardinals have lost four in a row and play a Monday night game at home against unbeaten Chicago in their next contest. ... Johnson's rushing total was his lowest since he gained 34 yards in just seven carries against Philadelphia on Oct. 2, 2006. ... Edgerrin James, who gained 71 yards on 24 carries, said the Cardinals are "making a lot of progress, but we still do stupid things. We're doing some of the stupidest things you can imagine."
