Yeah, the ACJ space is almost gone and the suprahumeral space is a bit decreased.
That combination would cause subacromial impingement and/or pain on abduction beyond 90 degrees.
Incidentally it looks like there's a little smooth traction spur on the underside of the acromion that suggests an old coracoclavicular ligament injury. That's rugby for you.
By the way, if you look at the very bottom of the second image, in the lung field you'll see a very small round opacity. Some folks might think 'oh no he has a spot on his lung' but it's an example of looking at a vessel on end, kind of like if you took a hose, layed it on a table and xrayed it, then turned the hose so that the opening was facing you and xrayed it again. The horizontally oriented hose would be more radiolucent, but when it was facing you it would look whiter because you're looking at the whole length of the hose. On a lung xray, the second example where it looks whiter (like a 'spot') would simply be described as normal summation of vascular structures.
