Curtis has been hurt since training camp with that Knee. Their was speculation he might either be put on PUP or even cut at one point. Maclin will likely draw starts from here on out, even when Curtis returns(and even that isn't concrete).
I'd say he's a WR3 just because The Eagles do spread the ball around so much.

According to Mike Lombardi of the National Football Post, the Eagles and Steelers will make Kevin Curtis and Limas Sweed available for trade this week.
The trade deadline is October 20. Lombardi also mentions Chiefs ILB Derrick Johnson as a player that potentially is available. A Curtis trade would move first-round pick Jeremy Maclin into the Eagles' starting lineup full time, but the veteran's knee injury and contract will make him difficult to move.
