Poor Baldric! This swelling could be due to trauma, it could be a lymph node swelling due to a localized infection or tooth problem, a reaction to an insect bite, or it could be an abcess. Given the absence of any additional signs, I would monitor Baldric for now. Should the swelling still be present in the morning, I. Would take him into the vet. If he shows up additional signs tonight such as difficulty breathing, difficulty swallowing, extreme lethargy, or anorexia, then I would take him into a vet right away.
