Koehn connected on 45-yard field goal in Thursday's preseason win over the Falcons.
Koehn is battling with incumbent Andrew Franks for the kicking job. While Franks, who was 13-of-16 last season with the Dolphins, certainly has a leg up, Koehn made a good showing on Thursday night while Franks missed his only attempt. Look for this kicking battle to come down to the final preseason game.
