The Dolphins have come to terms with offensive tackle Austin Jackson, Field Yates of ESPN reports. Jackson becomes the second of Miami’s three first-round draft choices to sign. The Dolphins now have signed nine of their 11 picks. Only cornerback Noah Igbinoghene, the team’s third first-rounder, and offensive guard Robert Hunt, a second-round choice, haven’t signed. Jackson, 20, started for two seasons at USC. He earned first-team All-Pac 12 last season and won USC’s John McKay Award for the most competitive spirit in 2018. The Dolphins made him the 18th overall choice.
