By now, everybody has been familiar with the antics from Detroit Lions head coach Dan Campbell. As honest as can be– and candid also– Campbell has been a treasure early on. But, as the regular season draws near, the Lions have a bit of a concern with some of their players.

Speaking with reporters on Tuesday, Campbell emphasized that he is concerned about the status for some of his players with the regular season weeks away, specifically citing the name of running back D'Andre Swift.

That could be an issue. According to Kory Woods of Woodward Sports Network, the Lions and Campbell don't seem concerned about the status of tight end TJ Hockenson, who suffered an injury to his shoulder but should be fine to go for their opener.

Obviously, Swift is the more concerning player here. The former Georgia star is set to explode in his sophomore campaign, but has been nursing a groin injury and might have trouble being ready for opening week. In his rookie season, he had 521 yards on the ground with eight scores and also added 357 yards and 46 catches in the passing game.

With new quarterback Jared Goff in town– as well as a new receiving group– Swift is easily in line for a heavy workload from the jump. As of now, Swift's availability is up in the air and the fact that Campbell is concerned is definitely not a good sign.
