The MRI showed some fluid but did not reveal any structural damage. Morneau may receive a cortisone shot at some point, but he is expected back in the lineup on Tuesday after sitting out Saturday and Sunday and the Twins' off-day on Monday.
"[Varecka] probably will see it [on Monday]," said Twins head trainer Rick McWane.
McWane also gave updates on the rest of the injured Twins, though there are no major changes for any of them.
Relievers Kevin Slowey (abdominal strain) and Joe Nathan (elbow soreness) continue to work in Fort Myers, Fla., at extended spring training. Slowey was scheduled to throw off a mound on Sunday, and Nathan is set to face hitters on Monday.
Tsuyoshi Nishioka (fratured left fibula) and Glen Perkins (strained oblique) are with Triple-A Rochester in Toledo, with Perkins having thrown a scoreless first inning on Saturday, allowing one hit. Nishioka was scheduled to play on Sunday, and Perkins will throw two innings on Tuesday night in Toledo.
Nishioka is expected to return sometime this week, and Perkins could be back soon as well.
Center fielder Denard Span, on the seven-day DL with a concussion, is "getting better," McWane said.
Eligible to return on Tuesday, Jason Kubel continues to feel better every day.
"He's still doing well hitting, [but] he's still a little bit sore running around," McWane said. "We're just progressing him as he tolerates."
