Dak had a 2nd surgery?
I'll answer my own question...
According to the link in the OP:
"Prescott
suffered a compound fracture and dislocation of his right ankle Oct. 11 in a win over the New York Giants, leaving the field on a cart and in tears. He underwent surgery that night, during which doctors' primary concern was preventing infection, and they did so successfully.
Sources say Prescott underwent a second -- and previously unreported -- procedure on the ankle about two months later to strengthen his deltoid ligament, clean out the ankle and make it more structurally sound. That procedure wasn't directly related to the October surgery; rather, doctors then spotted issues related to past injuries to the same ankle, and so once the risk of infection was eliminated, they went back in to clean up the rest.
After the second surgery in early December, Prescott had to take about a week off from rehab to let the wound heal, but it improved the stability and integrity of the ankle and should accelerate his overall recovery, per sources. He's now walking without issue, doing weight-bearing exercises and is expected to be ready for action long before the 2021 season begins.
That's one reason there are no medical concerns, sources say, for the Cowboys with regard to offering Prescott a nine-figure contract that would put him among the NFL's highest-paid players. If anything, Prescott is considered a little ahead of schedule in what was initially pegged as a four- to six-month recovery."
Sounds very good!
