The Oakland Raiders wasted no time getting business done with their top pick.
NFL Media's Albert Breer reported Thursday that linebacker Khalil Mack has signed a standard four-year contract with a fifth-year option and offset language, according to a source. The pact is fully guaranteed and worth $18,677,002, per Breer.
Financial terms of the deal have yet to be disclosed on Mack, the fifth overall selection in the 2014 NFL Draft. Last year's No. 5 pick, Detroit Lions defensive lineman Ziggy Ansah, signed a four-year, $18.595 million contract that included a $11.9 million signing bonus.
Mack had been floated during the pre-draft process as a potential first overall pick. He should be an immediate contributor on Oakland's improving defense.
