The Dolphins have come to an agreement with one of the team’s three 2020 first-round picks, locking up former Alabama standout Tua Tagovailoa to a four-year deal that features a team-option for the fifth year.

Tagovailoa, who was selected fifth overall in April’s NFL draft despite suffering a season-ending right hip injury in November, will receive $30.28 million over the first four years of the deal, according to a league source.

He’ll receive a signing bonus of $19,578,500, and all four years of his contract are fully guaranteed. That means if Tagovailoa suffers a medical setback that ends his career prematurely or the Dolphins choose to release him before the deal expires, he’ll receive all of the remaining $10.7 million owed, which is standard for players selected in the first round.

Dolphins' second-round pick Raekwon Davis also signed his four-year rookie contract on Monday.

Davis, a defensive tackle the Dolphins selected with the 56th pick during last month’s NFL draft, will earn $5,655,510 and receive a signing bonus just shy of $1.7 million. ESPN first reported the signing.

... Panthers offensive tackle Russell Okung says he’s appealing a decision that denied a claim he brought against the National Football League Players Association alleging unfair labor practices. The National Labor Relations Board last Thursday dismissed charges Okung brought against the NFLPA.

Okung has been outspoken against the collective bargaining agreement between the NFL and the NFLPA that was ratified by players on March 15, contending the players’ union violated its own voting procedures during the approval process. Okung’s lawsuit contends the CBA proposal never should have been sent to individual players for a vote after the union’s executive committee initially voted to reject approval of the CBA, 6-5.
