The Twins placed Gibson on the 10-day injured list Sunday after he was diagnosed with ulcerative colitis.

EDGE Analysis

Minnesota hasn't revealed a timeline for Gibson's return to baseball activities while he tends to the inflammatory bowel condition. With Gibson at least unavailable for his upcoming start Wednesday in Boston, the Twins will likely to turn to one of a pair of September callups, Devin Smeltzer or Lewis Thorpe, to take the hill or opt to fill the right-hander's spot in the rotation with a bullpen game.
