Lions quarterback Matthew Stafford received a $27.5 million signing bonus when he agreed to a contract extension last July but agreed to defer $17.5 million of the payment. That balance is due Friday, reports the Detroit Free Press.
The bonus already has been accounted for in the Lions' salary cap.
Stafford ranked third with 4,650 yards last season but his completion percentage (58.5) declined and his interceptions (19) rose for the second straight year, the paper noted.
