Glad that he did well.
What about a frozen raw marrow bone? or a black Kong stuffed with PB and kibble and then frozen? or a bully stick?
He does not have to be too quiet...just don't let him jump or run around. You can take him for a short leashed walk, 2 or three times per day.
They heal up very fast, and in a short time he will be back to normal exercise.
