Brandon Marshall's values after week 4

Danny Trevathan seems to be on his way back to week 5. I do not have much bench space currently. After this week, do you recommend drop Marshall to pick up Trevathan? Or is it smart to keep both until how the situation fold out for a few weeks after Trevathan returns?

I would drop Marshall for Trevathan after this week. I would have to imagine Trevathan gets his spot back with Marshall waiting in the wings to take over for Irving.
