ESPN's Adam Caplan reports that the Philadelphia Eagles have agreed to a contract extension with Right Tackle Lane Johnson on a six year deal that is worth $63 million with $35.5 million guaranteed.  Johnson is now locked up through the 2021 season.

Johnson was the Eagles first round selection in 2013 after playing Left Tackle at University of Oklahoma.  In the NFL Johnson has played the majority of his time with the Eagles at Right Tackle.  In 2015 Johnson played at Left Tackle when Jason Peters was injured.

This new extension gives the Eagles the insurance of having a starter on the roster who can play either Starting Tackle position.  With Jason Peter's contract is through the 2018 season, the expectation is that Johnson would be the air-apparent to become the next Left Tackle whenever Peters' time in Philadelphia is over.
