The Miami Dolphins are adding free agent running back Jake Funk to the practice squad, the team announced on Tuesday. The move comes shortly after news broke that rookie running back De’Von Achane sustained a knee injury during the team’s Week 5 victory over the New York Giants and is expected to miss several weeks. The team could place Achane on injured reserve, preventing him from playing for at least the next four weeks. That move could work in Miami’s favor, with the team’s bye week coming after their next four games, allowing additional recovery time for Achane.
