"I don't know," Fitzgerald said Thursday when asked about playing next year, via Darren Urban of AZCardinals.com. "I'm going to take some time, figure it out. I'll let you know though."
The Cardinals announced Fitzgerald's contract extension in November, though head coach Bruce Arians dodged questions about whether that meant the All-Pro wideout would actually play next season.
"I just said 'Congrats' and that was about it," Arians said.
Fitzgerald has been the face of the Cardinals since being the No. 3 pick in the 2004 NFL draft. He's made the Pro Bowl 11 times and holds franchise records with 1,217 receptions, 15,371 receiving yards and 109 receiving touchdowns.
The 34-year-old is eight receptions away from reaching 100 and 18 receiving yards from reaching 1,000 for the third consecutive season. No other Cardinals player has more than 33 catches or 490 receiving yards in 2017.
