The Tigers entered Monday evening two games back in their pursuit of a wild-card spot.

Unfortunately, Detroit's path to the postseason might've gotten a bit tougher during Monday's game against the Twins. That's because left fielder Justin Upton departed with a strained calf:

Officially, the Tigers are listing Upton as being day-to-day, though it's fair to think he might miss a game or two if needed.

Upton hasn't had his typical season. He entered Monday batting .239/.297/.424 with 22 home runs. Four of those home runs had come in September -- noteworthy in part because his monthly high on the season was five home runs. Atypical season from Upton or not, he remains a sizable upgrade over Tyler Collins, who would figure to get most of the playing time.

The Tigers are dealing with all kinds of injury issues -- to Nick Castellanos, to Jordan Zimmermann, and nearly to Victor Martinez. For Detroit's trainers' sake, here's hoping Upton makes a quick recovery.
