Sources say tension with Dolphins had been mounting for weeks in practice

It was an extremely tense week in London surrounding the Miami Dolphins prior to them being embarrassed by the New York Jets and subsequently firing coach Joe Philbin upon their return to the United States. Frustrations have been mounting for weeks, and escalated Saturday during practice prior to the game. Philbin has also been struggling on how to handle his franchise quarterback, Ryan Tannehill, who had been getting rattled even in practice sessions. On Saturday during practice, Tannehill, after a couple of practice squad players forced turnovers, Tannehill made negative comments toward them, including saying: "Enjoy your practice squad paycheck, enjoy your practice squad trophy." Sources say this has been going on for the past few weeks as the practice squad players have been intercepting Tannehill and frustrating the former Texas A&M wide receiver turned quarterback. The frustration for Tannehill stemmed from the entire situation as well as the Dolphins haven't won a game since the season-opener. Tannehill is an extremely competitive person, and the struggles of the offense have angered him significantly. Philbin told the practice squad players to take it easy on Tannehill to not affect the young quarterback's confidence. However, that didn't prove to be an effective strategy.
