He really should have been checked over as soon as he fell, or at least by the next day. Since that was not done, you should really try to get him into the clinic in the morning (Saturday, 9/24) because head injuries are not to be fooled around with. In the meantime, watch out for abnormalities in his walking, does he squint when he looks at things, look for vomiting or seemingly being off balance. The fact that he now appears to have a broken blood vessel in his eye needs to be addressed IMMEDIATELY to make sure there are no lasting ill effects. It's fine to say that his insurance starts in Wednesday but even if it's not in effect yet he needs to go to the vet.
