Patriots sign Dion Lewis to new deal

The New England Patriots have signed running back Dion Lewis, a surprise contributor for them this season, to a two-year contract extension through the 2017 season, a league source tells ESPN's Field Yates.

Lewis can make up to $4.8 million in new money over the two new years. The deal also includes a $600,000 signing bonus. His base salary will be $800,000 in 2016 and $1.2 million the following year.

The 5-foot-8 Lewis has been a threat out of New England's backfield and in the passing game this season. He has 30 carries and 15 receptions in the Patriots' 3-0 start with two touchdowns.
