The Detroit Lions are actively trying to see if they can rework quarterback Matthew Stafford's contract during the NFL Scouting Combine.

Members of the Lions front office sat down with Ton Condon, Stafford's agent, yesterday in an effort to see if new deal could be worked out this offseason. Neither side came to an agreement, but Lions general manager Martin Mayhew said the meeting was fruitful.

"We did meet with Tom Condon yesterday," Mayhew said. "Me, Tom (Lewand?), Brian Xanders met. We had a preliminary conversation, and I think it was productive."

That is a good sign for Detroit.

Mayhew is currently trying to clear salary cap space, and Stafford's contract is a key component. Stafford's base salary is $12 million in 2013, but his salary cap hit is $20.3 million. He will earn $11 million in 2014 ($19.3 million salary cap number) and $15 million in 2015 ($17.7 million salary cap number). The Lions are at least six million under the salary cap right now.

"We discussed some things with Tom, he'll discuss things with Matthew and we will follow up with a second conversation," Mayhew said. "Sometimes these things move along quickly, and sometimes they take a little longer. We're prepared for whatever way it goes."
