The Denver Broncos are working on a revised contract with quarterback Peyton Manning before the team announces his return for the 2015 season, according to a report.

The delay in officially declaring that Manning will be back next season could be due in part to the the complicated nature of restructuring his deal, the Denver Post reported Wednesday.

Manning made $20 million in 2013 and also in 2014, but he is scheduled to receive $19 million in each of the 2015 and 2016 seasons.

Before a deal can be finalized, Manning also has to pass a team physical by next Thursday.

Manning cast some doubt about his return after the Broncos lost to the Indianapolis Colts in the playoffs in January, but he later said he plans to return in 2015, and general manager John Elway and coach Gary Kubiak are expecting him to play. Manning flew to Denver to meet with Elway on Feb. 12.

According to the Post, the Broncos did not conduct any interview with quarterbacks last week at the NFL Combine, an indication that they believe Manning will be back as well as backups Brock Osweiler and Zac Dysert.

According to another report, the Broncos and Manning’s representatives hope to bring closure to a revised contract by early next week. Manning’s current deal is scheduled to become fully guaranteed on March 9, the day before free agency begins in the NFL.
