Gray himself tweeted that the Steelers had let him go. No news source has reported the move as of 8:30 on Tuesday morning, so the move might not be official.
Gray's release may come as a mild surprise to some fans. Gray was an undrafted free agent out of Southern Mississippi and was supposed to be one of the more interesting players in the Steelers' UFA class.
The Steelers dropped several players earlier this week: wide receivers Eric Greenwood and Kenneth Moore, cornerback Kevin Dockery, and tight end Vaughn Charlton. They also waived/injured tight end Miguel Chavis and placed running back Baron Batch on injured reserve.
