ENGLEWOOD, Colo. (AP) -- The Denver Broncos might be without their most productive running back when they face the New England Patriots this weekend.

Correll Buckhalter, who sprained his left ankle against Dallas on Sunday and left the stadium on crutches, missed practice Wednesday.

Buckhalter got hurt after gaining 55 yards on five receptions and 37 yards on six carries against the Cowboys.

For the season, he leads the team with 267 yards on 37 carries for a whopping 7.2-yard average. He also has caught eight passes for 96 yards.

The Broncos will likely turn to rookie Knowshon Moreno, who has rushed for 249 yards so far, to start Sunday, with LaMont Jordan and Peyton Hillis getting some carries, too.
