This story has been updated with a quote from Cowboys tight end Jason Witten.
A Cowboys spokeswoman told the Missourian, "We actually don't know anything about that."
When the spokeswoman was asked if there would be a press conference in the next couple days, she said, "There's no official information at this time."
On Tuesday night the Cowboys website said coach Jason Garrett is scheduled to have his daily press conference at 10:35 a.m. Wednesday.
Both Schefter and Rapoport said the Cowboys are looking to sign Sam to the team's practice squad, not the active roster.
The Cowboys spokeswoman said when transaction information is announced, it will be available on the team's website.
According to NFL.com on Tuesday, the Cowboys have a full 10-man practice squad.
Sam had 10 solo tackles and three sacks during four preseason games with the St. Louis Rams. The Rams released Sam on Saturday when NFL teams had to trim their rosters to 53 players.
When St. Louis drafted him in May, Sam became the first openly gay player drafted by an NFL team.
Cowboys tight end Jason Witten told The Dallas Morning News in March his opinion about Sam joining the team.
"I don’t know the individual,” Witten said. “Obviously there’s going to be a buzz that that creates. Just like other situations that you see with those individuals. I don’t think that that would be an issue. I think obviously there’s going to be challenges, just like any time when you’re in that situation because you’re the first.
“You just have to respect that process. I do think that if he’s a good player, which he really seemed like in college, it’s so competitive that whatever it takes from that standpoint that gives you a chance to win. But there are going to be challenges, and I think it would be unrealistic if we didn’t think that.”
