Snakes can and sometimes will eat prey items too large for them to digest. This will often lead to a regurge because they simply cannot digest the prey item as well as the prey item makes them too slow and basically defenseless if they were to be approached by a predator. Fortunately, it's far more common for wild snakes because they have to be far more opportunistic than our captive pets.
A 31 pound burm was just recorded found with a 35 pound deer inside it, which it regurged. Proof they WILL eat food larger than they should.
But, to answer the OPs question, your snake will be fine. Once it gets past the throat it'll disappear in the wider part of the snake and digest just fine. Nothing to worry about, OP.
