The typical theory is that crickets should be no wider than half the width of the gecko's head. Larger than that *can* cause problems, so I'd carefully observe your little guy to make sure s/he's doing ok. My understanding is that it's usually a problem of them having a difficult time swallowing an item that's too large, so if the gecko got them down ok you're probably alright this time. In the future I'd try to be sure you're getting the size you need though. Perhaps there's a size in between the ones you usually get and these too big ones? (I know some pet stores stock a multitude of sizes, some only a few, so your mileage may vary on that.)
