(CBS) There has been “considerable progress” between the Bears and running back Matt Forte in working out a long-term deal, according to CBSSports.com’s Jason La Canfora.

“League sources said there has been considerable progress between the Bears and Matt Forte ,” La Canfora wrote Thursday evening. “There are still issues to hash out regarding the average per year on the deal over the first three years, and how it could compare to say Marshawn Lynch’s new deal, but there has been movement on what the deal might look like over five years.”

If a deal isn’t completed by Monday, Forte will have to play the 2012 season for the franchise tender of $7.7 million.
