Gordon has been dealing with two separate bone bruises in his left knee, which he suffered in the Patriots' October 10th win over the New York Giants. The injury occurred when he was attempting to make a tackle after fumbling the ball, which the Giants recovered.
If he is healthy enough to return before the end of the season, he could find himself playing for another team. The team used the "minor" injured reserve designation, which means the team has to release him once he is healthy. If that happens after the October 29th Trade Deadline, then Gordon would be placed on waivers, which is a real possibility since the receiver believes he is not too far from recovering.
He will be eligible for unrestricted free agency after the season, this after commissioner Roger Goodell lifted his suspension on August 16th following his issues under the league's substance abuse policy. In six games with Tom Brady this season, Gordon had 20 catches for 287 yards and one touchdown, as he becomes the second troubled receiver to see his time with the Pats end quickly, joining the much more troubled Antonio Brown.
