MANKATO, Minn. - An attorney for the second suspect arrested in the assault of Isaac Kolstad tells KARE 11 his client will claim self-defense.

"This young man has a perfectly viable defense and I'm confident that when all of the evidence is on the table, he will be exonerated," said Michael Padden.

Paddon's client, Trevor Shelley, is facing first and third degree assault charges for the attack that left Kolstad with severe brain swelling and a fractured skull.

Witnesses tell police it was Kolstad who threw the first punch before Shelley knocked him unconscious.

The other person charged, former University of Minnesota quarterback Philip Nelson, allegedly kicked Kolstad in the head after he fell to the ground.

From a legal standpoint we treat them both the same," said Assistant Blue Earth County Attorney Pat McDermott. "It will be for the medical providers to help us determine, if at all possible, the extent of the injuries caused by either of the individuals."

Kolstad has undergone several surgeries and remains in critical condition. Doctors have not expressed confidence about his recovery.

A fund to help the family has been set up here.
