Doing a thorough google search I could not find any mention of Akers having had surgery. That in itself says plenty.
But I did find a lot of articles that said something like this:
"You will need to wear a cast or a walking boot for 6 to 12 weeks after surgery. At first, it may be set to keep your foot pointed downward as the tendon heals. You may be able to put weight on your affected leg after a few weeks. But it will be several months before you have complete use of your leg and ankle." [

And yet he's running on a treadmill after 5 weeks bearing 70% of his weight?
My guess at this point: he didn't have surgery.
