CENTENNIAL — Exhausted, he fell and couldn’t get up.

Forward Martin Kaut, the Avs’ 2018 first-round draft pick (16th overall), was in a debilitated state after doing his timed skating test Friday to conclude Day 1 of training camp at Family Sports Center.

After completing three reps of skating the length of the ice 4 1/2 times, Kaut, 19, fell to his stomach against the sideboards, rolled around for several minutes and didn’t return to his feet until an assistant coach told him to “get up.”

He later apologized on Twitter, after seeing a video of his exhausting behavior.

“I’m sorry for this, it wasn’t professional,” Kaut wrote.

In his daily press conference, Avalanche head coach Jared Bednar defended Kaut because he hadn’t seen his test scores and assumed he gave it his very best.

“Would I like to see every guy completely exhausted and laying on the ice after the skate? Yes. That’s the goal. It’s not to pace yourself and make sure that you can do all three (reps) without a drop-off. It’s to go as fast as you can all three times and see if you can sustain it for three reps,” Bednar said. “That gives our training staff and strength coaches a real good indication on where they’re at. He may have significantly faster times this year than last year and he just pushed himself to the limit. So I don’t want to make it into a negative for him.”

Bednar said every player was told of the skating test and advised to train for it. Every player appeared exhausted but Kaut might have been the only one who couldn’t remain on his skates.
