Hicks first felt the pain in his forearm and elbow area while taking swings before Saturday's game and was scratched from the lineup. He tested it again on Sunday, but he still felt it, which caused the Twins to place him on the DL.
"He came in and felt a little bit better today but there's enough limitation there where we're afraid of risk in the short-term if we run him out there too soon," Twins manager Paul Molitor said. "We just want to make sure we get it right and make sure it's not a long-term deal."
Hicks, 25, hit .247/.293/.301 with a homer and two doubles in 28 games before the injury. He was hoping to avoid the DL, but said it still was an issue on Sunday.
"It bothered me to throw and to hit a little bit," Hicks said. "You can't help the team win with that."
Hicks, though, said he was happy for Buxton, who skipped Triple-A just like Hicks did when he made his Major League debut in 2013. The two had lockers next to each other during Spring Training, and became close.
"I think it's exciting," Hicks said. "I was in his shoes not that long ago. It's exciting to see a guy up here for the first time and making his first Major League start."
