NEW YORK -- Twins manager Paul Molitor told reporters before Monday's game against the Yankees that Byron Buxton's first rehab game on Sunday went fine without any migraine-related issues, and that he remained a candidate to return once eligible to be activated from the 10-day disabled list Wednesday.
But roughly an hour later, Buxton was scratched from Class A Advanced Fort Myers' lineup, as he fouled a ball off his left foot during Sunday's game. X-rays came back negative, which is a good sign, but his return could be delayed until the Twins return home to Minnesota on Friday for their three-game series against the Reds. Buxton was originally slated to play center field in rehab games on Monday and Tuesday before a potential return to the Twins on Wednesday.
"He didn't have a reaction with the migraines, which was a good sign," Molitor said. "We'll see how the next couple days go."
Molitor said the Twins' medical staff has been working with Buxton about his migraines, which have been a recurring issue for him. He missed time last July with migraines, and he said it's an issue that plagues him at least once a year. But Minnesota would like to get the situation under more control, although Molitor admitted it's a tough ailment to treat.
"There are attempts being made to make them more preventative," Molitor said. "There have been methods and suggestions about either to prevent it from happening or minimizing the effects. But I don't think there's an exact science about how to deal with migraines. Some things work well for some people and not with others."
Buxton, 24, was hitting .195/.233/.244 with four stolen bases in 11 games this year. Ryan LaMarre started in center field in his place on Monday.

Injury updates
• Right-hander Ervin Santana, who is recovering from early February surgery to remove calcium deposits from his right middle finger, is getting close to throwing off a mound for the first time since the procedure, Molitor said. Santana has been throwing on flat ground without any issues, and he has regained the ability to extend his finger while throwing. There's no exact timetable for his return, but throwing off a mound will be an important next step.
• Right-hander Trevor May, who is coming off March 2017 Tommy John surgery, threw his last live bullpen session on Monday, and he is slated to pitch in game action in extended spring camp later this week. May will then progress to a rehab assignment with Fort Myers. He's eligible to return from the 60-day DL on May 28.
