Before taking the practice field Wednesday, Shepard took the time to wish his mother a happy birthday on Instagram. That indicates that it is likely a low ankle sprain, which has a shorter recovery period than a high-ankle sprain.
The article states that the NFL Network has said "that doctors were examining his left ankle". This does not look good for the player or organization as it is a loss to the great Giants receiver core.
Raanan added "it doesn't look encouraging" for Shepard (via Schefter). As long as it is not a torn meniscus or a torn ACL as these injuries are much more hard to heal and come back from.
As a rookie last season, Shepard turned heads. They made the playoffs past year but lost to the Packers in disappointing fashion. As the third receiver on the Giants' depth chart behind Odell Beckham and Brandon Marshall, Shepard is little more than a late-round fantasy pick.
Either way, the Giants are hoping for the best outcome from this situation.
"It looks at this point like he has a rolled ankle, a basketball-type ankle, but we'll see how he responds to treatment", Ben McAdoo said. The veteran could sit out the next couple of days for rest.
