Miami Dolphins rookie linebacker Raekwon McMillan suffered an injury during Thursday's preseason opener against the Atlanta Falcons.
Armando Salguero of the Miami Herald noted McMillan was removed from the game with the knee injury. Later in the game, Andy Slater of 940 AM in Miami reported the Dolphins fear McMillan suffered a torn ACL.
McMillan, 20, was selected by the Dolphins with the No. 54 overall pick in this year's draft. With Koa Misi's offseason spinal fusion surgery, McMillan came into the season with an excellent chance to earn a starting position next to Lawrence Timmons and Kiko Alonso.
