Here is the video of Adam Schefter talking about the LCL surgery . . .
Source (ESPN):
sounds to me like they don't see a new tear in the ACL but are uncertain if the graft from the first reconstruction surgery he had in college is still ok or if it is failing and needs to be rebuilt . . . hopefully we'll find out soon enough . . . one good thing is there must not be a ton of swelling or they would have to hold off further on the surgery and they are doing it this week . . .
