Akiem Hicks’ big pay day on the eve of the start of the season means $15.5 million to him this year after the Chicago Bears signed him to a four-year extension.

The new contract, which was finalized on Saturday, the day before the season opener against the Falcons, ties Hicks to the Bears through the 2021 season and as he was already signed for the 2017 season, the new contract is worth a total of $53,006,450 over five seasons. Hicks got $48 million in new money and four new years in the deal negotiated by agent Drew Rosenhaus. He celebrated the contract with two sacks in the 23-17 loss to Atlanta.
