The veteran quarterback has agreed to restructure his contract to help the defending AFC champions get under the NFL's $120.4 million salary cap.
Ryan Tollner, Roethlisberger's agent, said the team approached the two-time Super Bowl winner about the deal, but added it would not affect the length or the money involved in the eight-year, $102 million deal the quarterback signed in 2008.
"We've reviewed it and agreed to it," Tollner said Monday.
The Steelers entered training camp about $10 million over the salary cap and last week released veterans Max Starks, Flozell Adams and Antwaan Randle El to shed payroll.
Roethlisberger wore Starks' No. 78 in practice Sunday as a tribute to his longtime teammate. The two were both members of Pittsburgh's 2004 NFL draft class.
Roethlisberger likely wouldn't sign any paperwork until Thursday.
Under the new collective bargaining rules, players who sign contracts are not permitted to practice with the team until Aug. 4. Tollner said teams typically move money from a player's base pay to their signing bonus to keep it from counting against the cap.
The 29-year-old Roethlisberger is coming off a solid season in which he passed for 3,200 yards and 17 touchdowns after being suspended the first four games of the season for violating the league's personal conduct policy.
Colbert acknowledged the team knew it would have to get creative with its finances after making a heavy investment last season in hopes of capturing a seventh Super Bowl title. There was no salary cap in 2010.
