Brewers general manager Matt Arnold revealed Thursday that Contreras playing through a minor knee sprain during the team's wild-card series loss to the Mets, Jack Stern of BrewerFanatic.com reports.
Contreras didn't have to miss any time because of the injury, but it did force a move from catcher to the designated hitter spot in Game 3 of the series. He will not require surgery on the knee and is expected to be fine by the time spring training rolls around with an offseason of rest.
