Kansas City, Mo. ? Running back Larry Johnson’s injured right foot “has made significant improvement,” the Kansas City Chiefs said Thursday.

Johnson, who rushed for more than 1,750 yards each of the past two years, was injured in the fourth quarter last week of Kansas City’s 33-22 loss to Green Bay. Coaches have said he would almost certainly not play Sunday against Denver.

A Denver television station reported earlier this week that Johnson had a broken foot and was out for the year. The Chiefs have insisted that all they know is that he has a mid-foot sprain and probably will not play this Sunday.

A news release by the Chiefs said Johnson had “less swelling and pain in his injured right foot.”

“His status will be re-evaluated again early next week with further exams and tests. His status for this week is doubtful to out,” the statement said. It was signed by Carl Peterson, the Chiefs’ president and general manager, and team physician Dr. Jon Browne.

The Chiefs also announced that tackle Jason Capizzi had been added to the practice squad. Capizzi, 6-8, 312, entered the NFL as a rookie free agent this year with Pittsburgh and was released before the regular season.
