T.J. Watt is eager to return to the field after a dry needling mishap led to surgery for a partially collapsed lung. The Pittsburgh Steelers linebacker hopes to play Sunday night against the Baltimore Ravens, with the AFC North title at stake. Watt, who missed three games because of the incident, called it a “fluke” and said he won’t use the treatment in the short term. He felt good after practice on Friday and is focused on helping Pittsburgh reach the playoffs. The Steelers went 2-1 in his absence and can win the division with a victory.
