NCAA Proposal Changes (Complete list)

Arm Sleeves. (Rule 3-5.7, page 65)—Arm sleeves are illegal unless worn for medical purposes. Rationale: Sleeves are unnecessary and inappropriate equipment without permission from a trainer or physician.

So a trainer can indicate that a player needs to wear arm sleeves for medical reasons. I find this strange. A trainer may be influenced more than an MD. What is the thinking here?
