Lions quarterback Matthew Stafford is on the verge of signing a "blockbuster" contract extension, reports ESPN.
The extension could be finalized as early as Tuesday. Stafford is signed through 2015, but the Lions have said they wanted to rework his contract since his salary-cap hit is $20.3 million for 2013.
He is currently slated to earn $11 million in 2014 ($19.3 million salary cap number) and $15 million in 2015 ($17.7 million salary cap number).
