Ames, Iowa ? Mysteriously and surprisingly, Kansas University running back John Randle spent most of Saturday dancing around on the sideline, trying hard to stay warm on a chilly, windy autumn afternoon at Jack Trice Stadium.

The sophomore had proven himself to be KU’s top offensive weapon this year, but his line from Saturday’s 13-7 Iowa State victory left onlookers scratching their heads in disbelief.

Two carries for two yards. One pass reception for zero yards.

Randle was on the field for four plays early in the second quarter and spent the rest of the game jumping up and down on the sideline, shaking his arms and searching for heat on a day that was cold in more than one way for the Jayhawks. Clark Green played in Randle’s place.

“He didn’t practice all week,” KU coach Mark Mangino said of Randle, who missed action in last week’s 41-10 loss to Oklahoma. “He had a couple of plays, and he couldn’t move. He couldn’t get around.”

That was all Mangino said about the situation. The third-year coach followed his strict policy and refused to discuss details of any injuries. That rule left a ton of questions unanswered following Saturday’s contest, which was marred by players leaving the field in pain.

Besides Randle, who showed no signs of being hurt on the sideline, Green, quarterback Adam Barmann, center Joe Vaughn and cornerback/wide receiver Charles Gordon all missed time Saturday because of injuries.

Only Barmann left for good, though. The sophomore appeared to hurt his throwing shoulder after being tackled in the open field after a four-yard scramble. He left the game one play later, and, after being checked out by trainers, was seen imitating the throwing motion apparently to see if he felt well enough to return.

Barmann went to the locker room late in the second quarter, though, and came out in the second half with a baseball hat on. Brian Luke took his place for the rest of the quarter, but Jason Swanson played quarterback for the entire second half.

“It was enough to keep him out of the game,” Mangino said of the extent of Barmann’s injury. “Whether it’s enough to keep him out for an extended period, I don’t know yet.”

Vaughn already was in the locker room when Barmann made the trip, the victim of what looked to be a wrist injury. The senior returned in the second half.

Green and Gordon also came off the field in pain during the second half, but both returned in the fourth quarter.
