Joel Edelman unsure on week one availability

New England Patriots wide receiver Julian Edelman has claimed that he doesn't know if he will be fit enough to play in week one of the season.

The 29-year-old suffered a leg injury at the start of training camp, and may be forced to miss their first game of the season against the Pittsburgh Steelers.

Edelman told ESPN: "Any time you're not able to go out there and play it's difficult, but it's part of the game. I'm just working hard, doing everything I can each and every day to improve myself each and every day."

Edelman has scored 14 touchdowns in six seasons for the Pats.
