The NFL found no specific violations in its investigation into allegations that draft prospects were improperly asked about their sexual orientation during the scouting combine in Indianapolis.
"Our review has not established any specific violations, but we have made it clear to our clubs what is acceptable when interviewing potential players and other job candidates," NFL spokesman Greg Aiello said in a statement Thursday.
The Washington Post, citing a person familiar with the investigation, reported the NFL is leaving open the possibility of punishing teams in the future if it is found later that a violation did occur in combine questioning.
The investigation was launched in Feburary after Colorado tight end Nick Kasa told ESPN Radio in Denver that during interviews with team officials at the combine: "[Teams] ask you, like, 'Do you have a girlfriend? Are you married? Do you like girls?'"
He did not identify which teams asked him the alleged questions.
New York Attorney General Eric Schneiderman urged NFL commissioner Roger Goodell in a letter he wrote last month to "issue a statement that any form of discrimination or harassment on the basis of sexual orientation by league teams or players against potential recruits or players constitutes a violation of state, local and, in some cases, contractor law and will not be tolerated."
Schneiderman reminded Goodell that discrimination based on sexual orientation is illegal in New York and in at least 23 other states where the NFL's 32 teams are based.
At the league's owners meetings in Phoenix last month, Goodell called it "unacceptable" to ask a college player at the scouting combine any questions about his sexual orientation. Goodell said team personnel were reminded at the meetings "what they can ask and what they can't."
In February, DeMaurice Smith, the head of the NFL players' association, said in a statement, "I know that the NFL agrees that these types of questions violate the law, our CBA and player rights."
