"It wasn't so much that the Broncos' play-calling ratio Sunday was 87 percent run, 13 percent pass.

It was that the Broncos went 87-13 run despite their top two tailbacks, Willis McGahee? and Knowshon Moreno?, being unable to play most of the game because of first-quarter injuries.

Moreno, who had a spectacular 24-yard run in which he hurdled a tackler, suffered a sprained ligament in his right knee.

Moreno will have an MRI today to determine if there's a tear, but the initial diagnosis has him missing Thursday night's home game against the New York Jets?.

McGahee suffered a strained hamstring on his fourth carry of the Broncos' opening drive.

"I'll be all right," McGahee said after the Broncos beat the Chiefs 17-10. "I could have come back in an emergency situation."

With Moreno and McGahee out, Lance Ball? rushed for 96 yards on 30 carries, quarterback Tim Tebow? had 43 yards on nine carries, fullback Spencer Larsen? had a career-high five carries for 17 yards and flanker Eddie Royal? had three carries for 19 yards.

The Broncos will have some other bumps and bruises to monitor."
