How Long Can a Beef Roast Keep in the Fridge?

[btnfood]

I opened up a Cryovac-packed beef filet yesterday, cut it into thirds, and rubbed them with olive oil, salt, and cracked pepper.

I realized , before searing the third piece, that two pieces were going to be enough. Now the third piece is seasoned and waiting in the fridge. I might have tried "dry aging" this piece, had I known in advance, but it is now olied and seasoned.I was wondering how long I can keep this meat before I risk it spoiling.
