NFL Nation reporters assess the top storylines to watch Thursday for every team.

Buffalo Bills
The Bills return to the practice field Thursday after an off day Wednesday, and the biggest story will be the health status of tight end Charles Clay, who was not spotted at Tuesday's practice. Clay, who had been receiving frequent stretching of his back/hip area during previous practices, is a highly-paid and important part of the Bills' offense, so his availability is important, especially after injuries last season. -- Mike Rodak
The Dolphins reportedly worked out free-agent linebacker Brandon Spikes on Wednesday.
