Broke 4 bones plus tore an ankle ligament would be especially unusual and bad. The fractures that go most commonly with ankle injuries are the lower ends of the fibula (skinny bone of lower leg) and tibia (shin). The most common bad version of this pattern would be a “trimalleolar” fracture: tibia in 3+ pieces and fibula in 2+. As bad as it is, there would be a ray of hope for being back on it in 6 weeks after surgery and on the field by November. Sometimes the tibia breaks through the weight bearing surface instead of around the edges (plafond fracture). That drops the chances of seeing the field this year close to 0. If he broke his actual ankle bone (talus), he’s getting into new levels of bad. To get to 4 separate bones, you’d add another to those, and it you’d be moving into “unlikely even to walk without a little bit of a limp” territory.
Bottom line, it probably is about how it sounds: no chance he sees the field before October at the earliest— even that would be a surprise— maybe never, depending on what “broke four bones” means.
