What might help Buddy's cause is that the refs didn't call a foul, a technical nor an ejection on Buddy. However, in the rule book it does say that the conference can look at a suspension afterwards for a fight. Flagrant 2 is mentioned 163 times in the rule book, trip is mentioned 4 times, suspension is mentioned eight times but punch isn't mentioned at all. The definition of a flagrant 2 is on page 48.
Page 106: The following apply to situations in which a fight has been reported by an official during his jurisdiction. When a fight is not reported by an official, the conference or assigning authority may invoke its own penalty. For the rules on suspensions for fighting. (See Rule 10-5)
Page 48: 2. Flagrant 2 personal foul. A flagrant 2 personal foul is a personal foul that involves contact with an opponent that is not only excessive, but also severe (brutal, harsh, cruel) or extreme (dangerous, punishing),while the ball is live. In determining whether a foul has risen to the level of a flagrant 2, officials should consider the following: a) The severity of the contact; b) Whether a player is making a legitimate effort to block a shot. Note that a player may still be assessed a flagrant 2 foul on an attempted blocked shot when there are other factors, such as hard contact to the head or the defender winding up or emphatically following through with the contact. Depending on the nature of the contact, or the result of the contact, this foul also could be considered a flagrant 1 or common personal foul; c) The potential for injury resulting from the contact (e.g., a blow to the head or a foul committed while the player was in a vulnerable position). Depending on the nature of the contact, or the result of the contact, the foul also could be considered a flagrant 1 or common personal foul; d) Any contact by the offending player to the groin area of an opponent which is not clearly accidental; and e) Any foul similar to the foul described in Rule 4-15.2.c.1.g in which the contact, or the result of the contact, is not only excessive but also severe or extreme. Note: The above acts represent examples of potential flagrant 2 fouls. Other acts may also qualify, if they meet the criteria of being not only excessive but also severe or extreme.
