The Tennessee Titans fell to a disappointing 27-20 loss in the season opener against the Miami Dolphins on Sunday afternoon, which was compounded by a few key players getting injured in the process, including Pro Bowl tight end Delanie Walker.

According to Adam Schefter of ESPN, Walker is likely out for the rest of the 2018 season due to a broken left ankle and ligament damage.

The injury occurred in the fourth quarter after he made his final catch of the game. He was brought down to the ground awkwardly, with his ankle being jammed underneath him. It was clear early on that Walker was dealing with a significant injury given the angle his ankle moved during the play. It was initially diagnosed as a dislocated ankle and associated future.

The loss of Walker is a significant blow that now takes away arguably Tennessee's most important asset in the passing game, as he has proven to be one of the top tight ends in the league over the last several years.

In his first five years with the Titans, Walker has notched at least 60 catches in each campaign while topping 800 receiving yards in the last four seasons, which are the most for a tight end in franchise history. He has also led his position in receptions (356) over that span.

Walker is coming off a season where he led the team with both 74 catches and 807 receiving yards in addition to three touchdowns. For all 12th year players in the league in 2017, he led in receptions, receiving yards, first down catches (43), and receiving yards per game (50.4).

Walker's injury, combined with the potential loss of quarterback Marcus Mariota for an extended period of time due to an elbow injury, could quickly put the team in a massive hole offensively that could see their year quickly go south. Nonetheless, the loss of Walker is a huge blow to the passing game for the rest of the 2018 season.
