New rules courtesy of the NCAA Playing Rules Oversight Panel were made official recently. The changes will be implemented during the 2019-20 wrestling season. 

The three of the four rules changes were about relaxing current standards with regards to uniforms (shorts are now allowed), hair (there are no more restrictions about hair length), and the hands-to-the-face rule (it will be reclassified from "unnecessary roughness" to an "illegal hold"). 

The fourth rule change will alter the sequence in which stalling violators are penalized. Each subsequent stall call will result in the following: warning, 1 point, 1 point, 2 points, disqualification.

The result of the hands to the face reclassification should result in providing the referees with more discretion, as explained by the NCAA as follows:

The panel approved the reclassification of “hands to the face” from an unnecessary roughness violation to an illegal hold. Rules for illegal holds indicate that “whenever possible, illegal holds should be prevented rather than called.” This will provide referees more flexibility to use verbal cues, issue formal warnings and/or stop the action as “potentially dangerous” before calling an illegal hold. Referees still may call an illegal hold for hands to the face without warning if they determine it is appropriate.
