Foster was not expected to participate in a lot of the Combine's activities due to his recent shoulder surgery.
Foster was and probably still is expecting to be a Top 10-15 pick, but situations like this can make his draft stock unknown. After seeming nearly impossible that Foster fall to 22nd overall earlier this week, the idea is now not completely ridiculous to think about.
The Miami Dolphins are an extremely linebacker needy team, and if teams take this scenario to be more than it is (I personally do not see this impacting Foster's stock), we could see teams pass on the 2016 Butkus Award winner.
That would bode quite well for the Dolphins, who had Laremy Tunsil, one of the 2016 Draft's best prospects overall, fall into their laps last year after a video of him with a gas mask was released just minutes before the draft started.
While this alteration is by no means as severe, it does stir up questions surrounding Foster.
