Max Unger has agreed to rework his contract to free up some cap space for the New Orleans Saints.

The center converted $3 million of his $4.5 million signing bonus, which will clear up $1.5 million in cap space in 2015, according to a source.

The bonus will be guaranteed. Unger’s base salary was not previously guaranteed.

The move gives the Saints $6.5 million in cap space.

Unger’s cap hit in 2016 will now increase to $6 million.
