I claim the ornamental design for a jersey, as shown and described.
FIG. 1 is a perspective view of a jersey, showing my new design;
FIG. 2 is an enlarged perspective view of the claimed region of FIG. 1; and,
FIG. 3 is a front view thereof.
The dot-dash broken lines adjacent to the shaded area represent unclaimed boundaries of the claimed design. The broken lines illustrating the jersey represent portions of the article that form no part of the claimed design. The broken lines illustrating the wavy boundary in FIGS. 2 and 3 represent boundaries of the enlarged views.
