The Vikings hope running back Adrian Peterson can make it back before the season ends, after September surgery to repair a torn meniscus in his knee. With exactly one month to go in the regular season, the current thinking is that Peterson could lose his race against time.

As one source with knowledge of the situation explained it to PFT, Peterson continues to work hard in an effort to get back, and he badly wants to return. At this point, however, it’s not certain that he’ll make it.

One obvious factor becomes whether Peterson’s presence will make a difference. If the Vikings slide out of playoff contention, why bother to rush Peterson back to the field for late-season garbage time?
