Spector, 'heartbeat' of Bills' D, leaves with injury

An crucial piece to the Buffalo Bills defense left their matchup against the Tennessee Titans with an injury.

Star edge rusher Von Miller left the Bills' game against the Titans with an injury. Miller, who has been a key part of the Bills' defense this season, left the game in the first quarter with a knee injury, according to the Bills.

Miller is one of the most important players on the Bills' defense. He is a four-time Pro Bowler and eight-time All-Pro. He has also been named the NFL's Defensive Player of the Year twice.

The Bills' defense has been one of the best in the NFL this season. They are ranked first in points allowed and second in yards allowed. Miller has been a big part of that success.

The Bills will need to find a way to replace Miller's production if he is out for an extended period of time.

The Bills have a number of options to replace Miller in the lineup. They could move Greg Rousseau to the outside and start Boogie Basham at defensive end. They could also sign a free agent or trade for a player.

The Bills are hoping that Miller's injury is not serious. But if he is out for an extended period of time, the Bills' defense will take a big hit.
