Brian Dozier dived after ground balls and threw himself into third base in an unsuccessful attempt to stretch a double into a triple on Friday.
But the Twins second baseman said he didn't feel any pain in his right knee until he tried to accelerate out of the batter's box while grounding out in the seventh inning.
"No, it was definitely coming out of the box my last at-bat," he said.
It was enough that the Twins sent Dozier out for an magnetic resonance imaging exam to make sure there was nothing structurally wrong with his knee.
"We just wanted to be safe than sorry so we wanted to get it checked," said Derek Falvey, Twins chief baseball officer. "It's just a knee contusion or something along those lines. Knowing Brian, he'll say he's ready to go and wants to play, but we'll give him a day and go from there."
A day? Dozier was ready to pinch hit Saturday.
"I'm going to be available [Saturday] for sure," said Dozier, who had started every game before Saturday. "It was just the timing of it. I'm definitely available and will be in there tomorrow."
Dozier has his batting average up to .275 with a home run and two RBI. His five stolen bases tie him for the major league lead. He's become the fulcrum of the Twins offense and was missed as the Twins faced White Sox lefthander Jose Quintana.
