Cincinnati Bengals wide receiver A.J. Green has shed his protective boot, marking a positive step in his recovery from ankle surgery.
Green told reporters on Wednesday that he has progressed to running on a gravity assisted treadmill, but he stopped short of placing a timetable on a possible return to the field.
"Just making sure I don't come back too soon and hurt it again," said Green, who worked out with Bengals strength and conditioning coach Joey Boese on Wednesday.
Green was carted off the field during the team's first training camp practice at the University of Dayton.
The 31-year-old missed seven games last season with an injured right toe, falling short of 1,000 receiving yards for just the second time in his eight-year career.
Green has 602 receptions for 8,907 yards and 63 touchdowns in 111 games since the Bengals selected him fourth overall in the 2011 NFL Draft.
