A player can receive an invite to the NFL Scouting Combine, but that doesn’t mean he’ll get to participate in it.

According to a memo obtained by NFL Media Insider Ian Rapoport, if a background check reveals misdemeanor/felony convictions related to violence, domestic violence, use of a weapon or sexual offense and/or sexual assault, that prospect won’t be permitted to partake in the combine.

That rule has been put in place beginning this year.

“It is important for us to remain strongly committed to league values as we demonstrate to our fans, future players, coaches, general managers, and others who support our game that character matters,” NFL Football Operations Executive Vice President Troy Vincent stated in the memo to NFL teams.

The memo also states that each invite must authorize a background check to begin with or else their invitation will no longer be valid.

Last year, that’s exactly what happened to Tennessee Volunteers linebacker A.J. Johnson, who had his invitation nullified just days before the combine. The decision came after he was indicted — not convicted — by a Knoxville grand jury on two counts of aggravated rape. That court case is still pending.

On Tuesday, his name was mentioned in a federal lawsuit filed by six women against the University of Tennessee.
