"The last three days, we've been preparing, but now you're playing against a team with a different uniform on, so it'll be good to see what happens there," Lambert said on Saturday.
Monday would mark Alexander Romanov's preseason debut in an Islanders jersey if he plays.
Lambert said Monday morning that Semyon Varlamov will start Monday night's game against the Rangers.
