Week 9 at New York Jets
With the addition of WR Kelvin Benjamin via trade, Jordan Matthews will settle into a role as the Bills' No. 2 receiver, where he is probably better suited. From a fantasy standpoint, his stock drops and that's not saying much considering the numbers he had been putting up—averaging just over 3 targets and less than 3 receptions per game.
If you have Matthews on your roster, he definitely should not be in your lineup, and finding a better option on the waiver wire is something you should consider.
