If the Atlanta Falcons are waiting for the NFL's current market price for marquee wide receivers to be set before offering Julio Jones a contract, they either will know the going-rate on Wednesday or will have to become the team to set the bar if they want to sign him before the season starts.

ESPN reported Atlanta and Jones' agent had not had talks on a contract extension for the former Alabama star, who led the NFC in receptions and receiving yards last season.

Jones is one of four Pro Bowl receivers in line for a new contract.

Dez Bryant of the Dallas Cowboys and Demaryius Thomas of the Denver Broncos had the franchise tag placed on them by their NFL teams in March. Because of that, if they don't have new deal by 3 p.m. CDT Wednesday, Bryant and Thomas can't sign contract extensions until the NFL year ends next March.

A.J. Green of the Cincinnati Bengals is in the same situation as Jones: He had the fifth-year option on his contract picked up by his team for the 2015 season. Green said earlier this week that he'll play out his contract and wait until the end of the season to work on a new deal.

Calvin Johnson of the Detroit Lions has the biggest wide receiver contract in the NFL. Signed in 2012 and somewhat reflective of a different salary structure in the NFL, Johnson's contract is for $113,450,000 over seven years. It's also the most lucrative wide receiver contract in terms of annual value at $16,207,143 and in guaranteed money at $48,750,000. Johnson is a five-time Pro Bowler and three-time All-Pro.

The No. 2 contract to Johnson's among NFL wide receivers belongs to Mike Wallace of the Minnesota Vikings. The five-year deal signed in 2013 is for $60 million - a $12-million-per-year average - with $30 million guaranteed. Wallace is a one-time Pro Bowler who'll be playing for his third team in four years in 2015.

The franchise-tag value for wide receivers in 2015 is 8.949 percent of the salary cap -- $12,823,000. That's what Bryant and Thomas will receive in 2015 unless they sign new deals on Wednesday. If they don't, the receivers will have to sign the franchise tender if they want to play.

Bryant tweeted on Monday he won't report to training camp if he doesn't get a new contract, and ESPN reported the wide receiver had told the Cowboys he'd skip regular-season games, too.

Denver and Thomas' representatives have exchanged contract proposals, according to reports, without reaching a deal. NFL.com reported on Tuesday not to rule out the possibility of Thomas' missing games.

ESPN also has reported that the NFL Players Association plans to file collusion charges against the Broncos and Cowboys if Thomas and Bryant don't sign contracts on Wednesday. Union officials think the teams discussed the contracts of the two receivers, which is not allowed by the NFL's Collective Bargaining Agreement.

Green was taken by the Bengals two picks before the Falcons chose Jones with the sixth selection the 2011 NFL Draft. The fifth-year option on their four-year rookie contracts amounts to $10,176,000 for the 2015 season - the average of the 10 highest wide receiver salaries in 2014. Both players could be franchise-tag candidates in 2016 if the teams can't reach contract agreements with them.
