Corey Nelson was signed by the Atlanta Falcons to play some reserve linebacker when they learned that starter Deion Jones would be placed on injured reserve, but now it appears that Jones’ replacement is dealing with an issue now, too.

Nelson had to limp off the field during the Falcons’ practice on Wednesday with a member of the team’s training staff with an unknown ailment, according to a report from The Athletic.

The extent of Nelson’s injury will be more clearly known on Wednesday afternoon when the Falcons unveil their first injury report of the week prior to the team’s game against the New Orleans Saints.

Needless to say, the Falcons can hardly afford another injury anywhere on the field.

Jones is one of three players the team has already placed on the injured reserve list, in addition to starting strong safety Keanu Neal and starting left guard Andy Levitre. Running back Devonta Freeman, defensive end Derrick Shelby, and edge rusher Takkarist McKinley are also dealing with new injuries right now.

Head coach Dan Quinn called the injuries to those three players as day to day.

Nelson is a former seventh round draft pick out of the University of Oklahoma, getting his first chance in the NFL with the Denver Broncos, staying with that organization through the 2017 season and was with the team during their Super Bowl 50 championship.

A torn biceps suffered during last season’s campaign ended Nelson’s year prematurely in October. From there, he joined the Philadelphia Eagles this past offseason when the free agency marketplace opened up, but he wound up one of that team’s initial roster cuts late last month.

Earlier this summer, Nelson was being considered for a starting role with the Eagles, who were looking at featuring a new face in the middle of their defense, but the plans did not work out, and Philadelphia parted ways with the player.

In his NFL career, Nelson has 105 tackles, six pass breakups, and one sack. He had 77 combined tackles in the Broncos’ Super Bowl campaign in 2015-16.

As a result of his move to the injured reserve by the team, Jones will have to sit out for the next eight weeks of the regular season before the Falcons can decide on whether or not he is healthy enough to return.

Should he be healthy by then, Jones would return on Nov. 26 against the Cowboys.
