Atlanta Falcons safety J.J. Wilcox left practice on Monday due to an apparent leg or knee injury, per Josh Alper of Pro Football Talk. Wilcox had difficulty putting weight on his right leg and had to be helped off the field by two of his teammates.

For a Falcons team that also has fellow safety Ricardo Allen working his way back from a torn Achilles he suffered last season, Wilcox being hurt as well would obviously be a worst-case scenario type of situation.

Obviously, we don't know the extent of Wilcox's injury just yet, but this does not sound like good news for an Atlanta ballclub that saw its defense ravaged by injuries in 2018.

Wilcox signed with the Falcons earlier this offseason. He split the 2018 campaign between the Indianapolis Colts and the New York Jets, playing in seven games and logging seven tackles.

The 28-year-old, who played his collegiate football at Georgia Southern, went undrafted but eventually landed with the Dallas Cowboys in 2013 and went on to total 38 tackles in 13 contests that year.

Wilcox then became a full-time starter for the Cowboys the following season, participating in all 16 games and finishing with 81 tackles, three interceptions, a forced fumble, a couple of fumble recoveries and five passes defended.

He would go on to spend the first four years of his career in Dallas before joining the Pittsburgh Steelers in 2017, playing in 12 games in a reserve role.

The Falcons are coming off of a season in which they won just seven games and missed the playoffs for the first time since the 2015-16 campaign.
