After he left in the first half Week 5 against Tampa Bay with a sprained shoulder, Saints tight end Jimmy Graham's availability for the next few weeks is in question. Because the Saints have a bye in Week 6, it's possible he won't miss any games, but that's obviously a best-case scenario.
We should know more in the days ahead, but if you own Graham in Fantasy, your only choice is to wait it out. You're not going to find an adequate replacement on the waiver wire, and though you may be a little disappointed with his rate of touchdowns so far, his role in the Saints offense is such that he could go for multiple scores any given week.
Making a trade, whether for a replacement tight end or to unload Graham, is putting the cart before the horse. I wouldn't advise either unless you get an offer you can't refuse. Even with this injury, I expect Graham to perform like a first-rounder the rest of the way, so dealing him for less than that would be selling him short.
If he does miss time, Benjamin Watson is the likely in-house replacement, and he might be one of your better choices if Dwayne Allen, Jordan Reed, Niles Paul and Jared Cook are all off the board.
