Mooney was limited at Thursday's practice due to an Achilles injury, Tori McElhaney of the Falcons' official site reports.
Mooney has been a revelation behind Atlanta's No. 1 WR Drake London this season. While he's surpassed 100 receiving yards just one time in 10 outings, Mooney has accrued a 46-684-5 line on 77 targets. Now with a health concern in tow, his status will be one to monitor as the week goes on to see if he may be in danger of sitting out Sunday at Denver.
