Big West rule is 5 + 3 reserves.

In the event of an issue beyond the control of the institution, a team shall be expected to
honor a scheduled contest if it can field a starting line-up and a suitable number of
reserves for that particular sport. A suitable number of reserves in the sport of basketball
shall be three players.

BTW, that section of the Big West bylaws also sets that standings are set by winning percentage if teams don't play a full conference schedule:

"In the event that all teams do not play a complete conference schedule, the final regular
season standings (and possible championship tournament seeding) will be based on
winning percentage in conference contests."

I can understand why some teams would be upset with UCD's use of this no contest provision. On the face of it, I would seem that the Aggies could play with a lineup of, say: Pepper, Johnson, Adebayo, DeBruhl and Rocak with Mani and Borra for depth and be somewhat competitive, but without a very good chance of winning. If this were the Big 12, as per DrMike, they would have no choice, but we have no idea if all those players are healthy. I would think that in order to have this game called, the Big West would require some kind of medical documentation, but HIPPA prevents it from being public. On th eother isseu, you'd think the Big West would clarify the rule as to how many players have to be out for a no contest decision. It seems that we are simply spinning our wheels without more information.
