After Deatrich Wise Jr. suffered a season-ending injury in Week 2, the Washington Commanders have added veteran pass-rusher Preston Smith to boost their defensive line. Per NFL Network's Tom Pelissero, Smith is going to sign with the Commanders ahead of Sunday's game against the Las Vegas Raiders. Head coach Dan Quinn announced on Monday that Wise would miss the rest of the season. He suffered a torn left quadriceps in Washington's 27-18 loss to the Green Bay Packers. The Packers dealt Smith to the Pittsburgh Steelers prior to the trade deadline last season.
