An MRI revealed that Cincinnati Bengals wide receiver A.J. Green has torn ligaments in his left ankle that is likely to sideline him six to eight weeks, a source told ESPN's Adam Schefter.
Green is not expected to be ready for the regular-season opener at Seattle.
He was carted off the field Saturday during the Bengals' first training camp practice of the season.
Green's left shoe was removed before he departed the field. Last season, he missed seven games with a right toe injury.
That campaign marked only the second time Green did not have at least 1,000 receiving yards in a season during his career.
