Gruden said there is a chance Griffin will play on Sunday against the Minnesota Vikings. Griffin has been out since Week 2, when he suffered a dislocated ankle.
Gruden reiterated Wednesday that Griffin's situation is now more mental than physical. The quarterback will return to the lineup only when the team feels he is properly prepared.
"We'll see it's all going to depend on how he does in tomorrow and Friday," Gruden said. "And moving forward, how I feel he's coming back. From a physical standpoint he looks good, now it's a matter of mental and getting back into the football part of it. If he looks good in that regard then there's a chance he could play and if not and he needs another week, he'll take another week."
