Mahomes master series aaron Donald missing

[kinkofkings218]

I have been grinding on this master series since October.  Finally got to mahomes but it's asking for many of the previous master series players.  Aaron Donald used to be on my lineup but he's not anymore and the only thing I can think is it went into one of the max badges sets.  How can I get another one?
