ST. LOUIS — The St. Louis Rams concluded their three-day mandatory minicamp with a game challenging the punt catching skills of their offensive and defensive linemen.

A device similar to a pitching machine shot the football more than 100 feet in the air and more than 75 yards down the field as linemen took turns trying to catch it.

No lineman was able to cleanly field any of the wind-blown balls.

"It was between the offensive and defensive lines, and whoever caught the most," Fisher said. "Then it got to whoever touches it."

Only two linemen -- rookie defensive end Jamarr Jarrett and second-year offensive lineman Kevin Hughes -- got their hands on the ball.

"We have to take a couple of them and ice them down," Fisher said of his linemen. "Harvey (Dahl) landed on his head."

Dahl was not injured, but it prompted Fisher to send out his players with return experience.

Wide receiver Danny Amendola, who has returned 116 kickoffs and 72 punts in his career, was the first player to catch one of the punts.

"Clearly, the big guys got an appreciation for how hard that job is," Fisher said. "Then, when Danny got up there and caught that first one, they understand now."
