Initially after Sunday's game, Twins manager Ron Gardenhire said he didn't believe Mauer's injury to be serious. Mauer is listed as day to day, but considering this is the same knee in which he tore his meniscus during his rookie year in 2004, the Twins are holding their breath.
"Hopefully it's just a couple of days and go from there," Gardenhire said.
Mauer injured his knee after grounding out to second in the sixth inning of Sunday's game.
"I was running down the baseline," he said. "It started getting a little worse and worse, and I thought it was the right time to get out of the game."
Mauer said he has no idea how bad the knee is, but that he will probably be out for at least a couple of days.
"I don't know. They say it's day to day. I really don't know a whole lot right now. Obviously, I'd rather not have this going on, but here it is."
The Twins will take a wait and see approach when it comes to Mauer. For the time being, Mauer's knee will get a heavy dose of ice and see how the knee is tomorrow.
"I'm just trying to get back on the field. I don't know a whole lot right now. I'm just trying to do whatever I can to get back there."
