Obi Melifonwu entered Wednesday as the only second-round draft pick without a signed rookie contract. Later that afternoon, he joined the group.
The safety from UConn put pen to paper on a four-year deal at the Napa Valley Marriott, allowing him to join pre-training camp activities. Veterans report on Friday and camp's first full-squad practice starts Saturday morning.
The pact took longer than the Raiders or Melifonwu had hoped. There's little room for fiscal movement in the rookie wage scale, but some contract language had to be hashed out before shaking hands.
Melifonwu is slotted to make $4,509,376 over the life of the contract, with a $1,419,544 signing bonus and a $819,886 base salary in 2017, per overthecap.com.
The Raiders have one draft pick left unsigned. First-round cornerback Gareon Conley hasn't agreed on a deal, though it's still likely that happens before the first full practice.
The Ohio State alum's situation could be complicated by an ongoing investigation into a sexual assault allegation stemming from an April 9 incident in Cleveland.
Head coach Jack Del Rio said in a Tuesday radio interview he expected unsigned rookie contract issues to be resolved soon.
