Twins first baseman Joe Mauer felt good during early batting practice Thursday. But it was a different story when he went through fielding drills.
He began to feel the concussion symptoms that were part of the reason he landed on the disabled list two weeks ago. So he backed off those drills and hopes Friday will be a better day.
But he is already preparing himself for the possibility he will not be activated from the 10-day disabled list during this four-game series against the AL Central-leading Indians.
"I'm disappointed because I was making good progress," he said, "but I don't anticipate it being a long or lengthy deal. I was hoping it would be a little bit better today."
Mauer planned to spend the night at Target Field and be around his teammates. But he remains cautious about doing anything to trigger symptoms. He preferred to speak to reporters Thursday without television cameras turned on, just to make sure the lights wouldn't affect him.
It's a setback for Mauer and the Twins, who need his .283 batting average and .404 on-base percentage back in their lineup like they need air to breathe.
Keep in mind that Mauer landed on the disabled list because of a cervical strain in addition to concussion symptoms. He passed concussion tests at the time, so he was not placed on the seven-day concussion DL, meaning he is not in the league's protocol. But he has been seeing area specialists about the symptoms nonetheless.
Twins Chief Baseball Officer Derek Falvey said there are no plans for Mauer to undergo more testing.
