Drop Eric Ebron for Tyler Eifert?

In a 14 man, standard scoring 4pt QB league–waivers are cut throat. Had Hockenson but after injury paid $9 for Ebron this week. Is it worth it to throw Ebron back to the wolves on the off chance Eifert has a monster week? Especially after paying for him and chancing not getting him back for the rest of the season?
