The Detroit Lions want to work out a new contract with Matthew Stafford.

Before they go about tackling a deal with the quarterback, they have restructured contracts for two of the team’s other star performers.

Brian McIntyre of Yahoo! Sports reports that wide receiver Calvin Johnson and defensive tackle Ndamukong Suh have both had their contracts modified to clear up additional cap space for this season.

Per the report, the Lions reduced Johnson’s base salary from $5 million to $715,000, converting the difference into a signing bonus that can be spread over the remaining life of the contract. In doing so, the Lions reduced Johnson’s cap number for this season from $12.2 million to a little less than $8.8 million, creating a saving of nearly $3.5 million.

In Suh’s case, Detroit renegotiated his contract to create $7.68 million in space. Of course, the flip side is that both players will have even greater cap numbers in coming seasons.
