NFL owners and players still haven't reached an agreement.
NFL Commissioner Roger Goodell and Players Union chief De Maurice Smith took a break from negotiations to meet with NFL rookies in Florida Wednesday.
A new rookie wage system is a key part of ongoing negotions on a new collective bargaining agreement.
If the talks fail, the season is at risk.
"It was a great opportunity for us to sit with the rookies, they obviously have lots of questions to be answered, questions answered the best we could," Goodell said afterward.
A fifth set of "secret" meetings between Goodell, Smith and their staffs is continuing with the start of traditional NFL training camps now just three weeks away.
The lockout is four months old; NFL players continue to work out on their own.
The talks are slated to run through Friday.
Meanwhile, the clock is ticking on the NBA's current collective bargaining agreement.
That labor deal expires at midnight.
Many experts feel the NBA owners and players remain far apart on key issues with yet another lockout looming.
