Narrative:
FL310 cruise flight. I was PNF. We were talking to ZID. We were given a clearance to cross the knox VOR 30 mi east of knox VOR FL250 which I acknowledged. I set 250 in the altimeter window and the captain correctly verified. ATC queried us if we were going to make the crossing at 30 mi east at FL250. We were already over the crossing restr at that time at FL310. We initiated immediate descent to FL250 and ATC did not require any further actions. First officer and captain forgot about the crossing restr. (Contributing factor) first officer was up early morning, had 4 hours sleep that night.
