Eberle skated with Hall and Draisaitl in practice today. RNH with Pouliot and Yakupov was the other forward line with fantasy relevance. Based on that, I would say Eberle is good to go this weekend.
That leaves the decision to you on whether or not you should drop Gallagher for him as that would be my first choice on who to drop.
Can you keep Eberle on IR for a little while? I would hate to see Gallagher dropped with those cats. Of course in a 7-team I guess there will always be talent on the WW.
