I would probably do it. Between the three guys you have a solid base in which you can play match ups throughout the playoffs. If Gordon is only out a couple of weeks you may not be able to trust him when he first comes back anyway.
Is this for redraft or dynasty? If this dynasty I think that is a fairly easy accept if you can keep all of them.
In a redraft I would be a little more hesitant as this year Cook and Adams seem to be in a time share and Jones still isn't being used enough (why was he out of the game yesterday in the final couple drives when they needed a big play?). However, with Gordon being out multiple weeks (at least that is the current belief) there is a chance that Ekeler splits time with Justin Jackson from here on out. I think I pull the trigger either way (dynasty or redraft).
