Probably Jones fracture if it’s the 5th metatarsal.
The 5th connects to the 4th unlike the rest & it’s a common sports injury, especially on the NBA.
Usually happens from hard start, stop movements.
I had that injury in both my feet in my 20’s. No surgery. My left healed completely & my right never did, causing a non-union fracture. It formed around the bone to protect it. I was advised to never play quick change, start/stop sports like basketball, football, racquetball, tennis, etc… ever again.
Even with surgery, he has a high chance of it being a problem with his size & playing football.
