Per ESPN's Jordan Raanan, Tate acknowledged he's "responsible for what is put in my body" but said the doctor told him he had prescribed the medication to other NFL players:
"I think ultimately just because the doctor had said, 'No, it's not a banned substance and I have prescribed it to other NFL guys.' If the doctor said I'm not sure, I 100 percent would have looked into it. If the doctor had never said he had given it to any other NFL players, I 1000 percent would have looked into it. I have gone through the TUE process for a couple medicines and I completely understand it."
Tate also noted his camp is "examining all of our options," including legal action, against the doctor, per Pro Football Talk's Charean Williams.
The NFL announced Tuesday that Tate will miss the first four games of the regular season after his appeal was denied.
ESPN's Adam Schefter reported July 27 that Tate was facing a suspension for violating the NFL's performance-enhancing drugs policy. The nine-year veteran issued a statement on Twitter, explaining he stopped taking the medication upon realizing it contained a banned substance and self-reported it to the league before the results of his drug test came in.
In addition to being suspended four games without pay, Tate lost "full guarantees" on his $7.975 million salary next year, per NFL Network's Mike Garafolo. He signed a four-year deal with the Giants in March.
Tate will be eligible to return for New York's Week 5 game against the Minnesota Vikings. The 31-year-old had 74 receptions, 795 yards and four touchdowns with the Detroit Lions and Philadelphia Eagles last season.
