Wood suffered permanent nerve damage at work and could no longer drive a ready-mix concrete truck, though he could drive other trucks. He asked for a reassignment but, since his employer did not have another job for him, he was terminated. He was somewhat limited in walking and in performing certain work functions. He also claimed discrimination based on the fact that his injury resulted in impotence, substantially limiting him in a major life activity. Is he covered? [Wood v. Crown Redi-Mix, Inc., 339 F.3d 683 (8th Cir. 2003).]
