Obviously, that was NOT Jesus' shroud.
Actually, those passages confirm for me the shroud covered Christ. As I pointed out, see above the reference to the head cloth (napkin in my Bible) in Spain with the same rare blood type found on the shroud.
The Sudarium of Oviedo: Its History and Relationship to the Shroud of Turin
Excerpt:
Such a cloth is known to have existed from the gospel of John, chapter 20, verses 6 and 7. These verses read as follows, "Simon Peter, following him, also came up, went into the tomb, saw the linen cloth lying on the ground, and also the cloth that had been over his head; this was not with the linen cloth but rolled up in a place by itself." John clearly differentiates between this smaller face cloth, the sudarium, and the larger linen that had wrapped the body.

Not only does the blood on the head cloth in Spain match the blood type found on the Shroud, but the blood stain pattern also matches the pattern found on the Shroud.
I never knew anything about this other piece of cloth in Spain until a couple of weeks ago, when two men made a presentation after Mass about the Passion and the connection with the Shroud.
It was also discovered that a bacteria that creates a coating, or sheen, was growing on the outside of the Shroud which is believed may have interfered with the accuracy of the carbon dating.
There were also mold spores found on the Shroud that are only native to Jerusalem. Also, I recall something about a certain type of flower appearing on the Shroud and buried with the body as custom is found only in Jerusalem. It was very interesting.
