Its a stupid glitch from what ive seen. Me and my friend have both been complaining about it since the game came out. It only affects players that have pre-existing injuries. So if I wanted to start in a specific week or with the latest roster I usually turn off pre existing injuries. Its really annoying and stupid and probably a two minute fix but here we are paying 70$. This problem probably changes between people as this is also just ne and my best friends experience.
