PHILADELPHIA -- On the heels of a report that the Eagles are trying to extend defensive end Brandon Graham, the contract numbers for the extension handed out to defensive tackle Timmy Jernigan are out -- and they are massive.

As expected, the four-year, $48 million deal Jernigan signed with the Eagles earlier this month is back loaded, but it does increase Jernigan's cap number this season and takes a decent chunk of their projected cap space for next offseason.

Here is the breakdown, according to OverTheCap.com:

2017:

Cap Number: $3.3 million (up from $1.39 million)

2018:

Cap Number: $5 million

2019:

Cap Number: $13 million

Dead money if cut: $7 million saved, $6 million in dead cap

2020:

Cap Number: $14 million

Dead money if cut: $10 million saved, $4 million in dead cap

2021:

Cap Number: $14 million

Dead money if cut: $12 million saved, $2 million in dead cap

Based off of those figures, it seems like Jernigan is a lock to be here through the 2019 season, and the first time the team could realistically cut him is prior to 2020. If Jernigan is still playing at a Pro Bowl level at that point, the Eagles would likely try to re-work his deal.

Assuming both Jernigan and defensive tackle Fletcher Cox make it to the 2019 season, the Eagles will have $35 million in cap hits tied into their starting defensive tackles.

The decision to extend Jernigan takes the Eagles' cap space into the red for next offseason, as according to OverTheCap.com, the Eagles are now projected to be $400,000 over the cap in 2018.

That number will change, but it points to just how cap strapped this team is for next year and free agency.
