Hendriks will be evaluated by the club upon his return, as the Twins are still not sure when he'll be ready to rejoin the rotation. Right-hander Anthony Swarzak, who allowed just one run over five innings on Sunday in place of Hendriks, is tentatively scheduled to start again on Thursday against the Angels.
"I'm going to come to the field tomorrow and do some running and see how I recover," said Hendriks, who wasn't sure what made him sick. "I didn't lose any weight, which is a plus. It should take a few days, so we'll see how it goes."
Right-hander Jason Marquis could also rejoin the rotation soon, as he's scheduled to make his second start with Double-A New Britain on Thursday. Marquis, who missed two weeks of Spring Training tending to his 7-year-old daughter, who was injured in a bicycle accident, is expected to throw around 100 pitches.
He fared well in his first start in Double-A, allowing just one run over six innings while throwing 75 pitches.
"He's done nothing to disappointment," Twins general manager Terry Ryan said. "Everything he's told me is true. He's working. He threw pretty good the other day."
Ryan said the club still hasn't set an official date for right-hander Scott Baker to get a second opinion on his right elbow from Dr. David Altchek in New York this week. An MRI taken on Friday showed no new damage from the one he had last July, after which he missed 18 games with a strained flexor muscle.
