A report from USA Today on Friday said Oklahoma running back Joe Mixon did not get an invitation to the NFL Combine. The report cited anonymous sources, because the official invitation list has not been made public yet. Last year, the NFL told its teams it would not allow players with convictions for domestic violence, sexual assault or weapons offenses to participate in the combine. Given the past cases of domestic violence in recent years, the NFL clearly wants to avoid the publicity caused by having a player who’s been involved in similar situations attending the combine. Even though Mixon won’t be at the combine, he can still get invitations to work out for specific NFL teams and will likely participate in OU’s Pro Day, where scouts from around the league visit Norman to look at potential pros from the Sooners.
