The Dolphins have placed left tackle Austin Jackson on IR due to a foot injury he suffered during Sunday’s loss to the Seahawks, as Barry Jackson of the Miami Herald reports (via Twitter). Although the rookie LT would be eligible to return after three weeks under the modified rules for 2020, Barry Jackson says in a full-length piece that head coach Brian Flores was non-committal when asked if Austin Jackson would be back this season.

Indeed, Flores said the team is looking for a “long-term replacement” for Austin Jackson, so it sounds as if the USC product very well may miss the rest of the year. Though Miami has several options, Barry Jackson suggests that Julie’n Davenport — who filled in for Austin Jackson during the Seattle game and played well — might have the first crack at the LT job.

Austin Jackson was the second of three first-round choices that the Dolphins had in this year’s draft. He was thrown into the fire right away, and he acquitted himself reasonably well. He had not allowed a sack this season, and he recently earned praise from his position coach.

“Austin has had a great start to this season,” offensive line coach Steve Marshall said earlier this week. “He’s learning every time he’s going out there. I’m very excited for his future. He can be a heck of a pro offensive left tackle.”

Pro Football Focus’ advanced metrics considered Austin Jackson to be a below-average performer in terms of both run-blocking and pass-blocking, but he has certainly shown enough flashes to justify Marshall’s enthusiasm. One wonders if Austin Jackson’s absence will have any bearing on Flores’ decision as to when to insert rookie QB Tua Tagovailoa into the starting lineup.

To take Austin Jackson’s place on the roster, the Dolphins have promoted rookie running back Salvon Ahmed from the practice squad. As Barry Jackson observes (via Twitter), the team has liked what it has seen from the UDFA, though he will be joining a crowded RB depth chart.
