And here’s why those Super Bowl predictions often end up being meaningless.

Packers running back Ryan Grant’s “significant ankle injury” from Sunday was sufficiently significant to end his season.

Jay Glazer of FOX reports that Grant will be placed on injured reserve with ankle and leg injuries.

Emerging as the starter in 2007 after a string of injuries to others on the depth chart, Grant rushed for 1,203 yards in 2008 and 1,253 in 2009.

In-house options to replace Grant are Brandon Jackson and John Kuhn. James Johnson is on the practice squad.

Available veterans include Willie Parker and . . . and . . . Shaun Alexander?
