Yes, you can. Lineup changes can be made whenever you want, and you don't need to submit anything for "day to day" injuries if the player is not going on IR or LTIR. Most players in this league are playing through things on a regular basis that would qualify as "day to day". Teams did it all the time in the game before the deadline for high-value players. They continue to do it; they've just stopped caring about pretending it's anything other than trade-related. What IS heavily scrutinized and inspected however is injured players being traded, which just makes your unsupported claim even more ridiculous.
Even according to your own so-called "documented evidence", Foligno was "day to day", and then had 2 weeks in quarantine to heal, so even if he was "injured", he was fine by the time he played for us. He looked great, went PPG, and then suffered an injury on May 3rd that has been well documented - in real time, in a behind-the-scenes TV series, and from the words of the person himself.
What Foligno experienced with us, what took Foligno out of games with us, what made Foligno play at 50% with us was brand new, and happened while with us, after the trade.
Well, multiple teams were willing to offer the same, but either way, that's a different argument than making false claims about his injury.
