"They were going to have me run half the camp at defense and half the camp at offense," Kiel said in a telephone interview Thursday afternoon.
Kiel's camp experience in Lawrence, however, was over before a half hour had ticked off the clock.
"I was at (Missouri's) football team camp and then went from there (and) drove to KU's one-day camp and I was running my 40 and pulled my hamstring. So I've got to take the rest of this month off…
"They tested me on my vertical and shuttle run, and I was running my 40 and went down like I got shot — pulled my hamstring."
Kiel has already begun rehabbing his injured hamstring but he had to cancel his camp plans for the rest of June.
Kiel said that Kansas and Northwestern are his current favorites. The Jayhawks, he said, "are showing me a lot of interest."
"Right now I like KU a lot (and) Northwestern," Kiel said. "I was going to go visit there. But right now I like KU a lot."
He is also receiving interest from several other Division I football programs, including Indiana, Michigan State, Wisconsin and Illinois. He called Wisconsin's current interest in him "mild." Last month, he received phone calls from football coaches at Kansas, Ball State and Indiana.
Kiel is also receiving interest from basketball programs such as Butler, Southern Illinois and Drake. Last season Kiel averaged 12.9 points, 7.2 rebounds, 3.1 assists and 2.4 steals per game, while playing a wing position. He said he does not have a preference between football and basketball. "I love both of them," he said.
On the gridiron Kiel played tight end, linebacker and defensive end. He caught two passes for 14 yards and had 42 tackles and two sacks.
Most college programs, Kiel said, are recruiting him to play tight end.
