Floyd suffered the unusual injury — to the olecranon, the bony tip of the ulna that sticks out at the curve of the elbow — while pitching against Washington on Thursday.

The ulna is rudimentary, being represented by little more than the olecranon.

From this origin it is directed towards the elbow, to be inserted into the olecranon, either directly or by the medium of the tendon of the long portion.

Its anterior fossa for the reception of the coronoid process is filled up with a bony growth, and, at the same time, the olecranon process is curved strongly downwards.

The ulna is best seen at its proximal end in the specimens from the Cambridge Greensand, where there is a terminal olecranon ossification forming an oblique articulation, which frequently comes away and is lost.
