Packers running back Josh Jacobs is having another strong year. Whether his performance continues on Sunday at Arizona remains to be seen.

Adam Schefter of ESPN.com reports that Jacobs is a “true game-time decision” due to a calf injury and an illness. (You might wonder: what’s the difference between a “true game-time decision” and a “game-time decision?”) Regardless, the Packers don’t expect to know whether Jacobs will be able to play until Sunday.

Some of the other notable players who have been game-time decisions include LaDainian Tomlinson, who did it four straight times in 2006, Chris Johnson (2009), Ricky Williams (2002), and Jim Brown (1962-63).

First and foremost, Jacobs has to be able to play. For now, that status is apparently still up in the air — truly a “true game-time decision.”
