Out multiple months
Butto will miss the next 2-4 months after undergoing surgery Saturday to remove a blood clot from his right arm, Justice delos Santos of The San Jose Mercury News reports.
Analysis
Butto was diagnosed with a blood clot after leaving his appearance Wednesday against San Diego with arm fatigue. His timeline leaves room for him to return to the Giants' bullpen before the end of the season, though that likely won't happen until closer to the All-Star break.

Diagnosed with blood clot
Butto was diagnosed with a blood clot in his right arm and will undergo a procedure Friday to remove it, Alex Pavlovic of NBC Sports Bay Area reports.
Analysis
Butto exited his appearance Wednesday alongside a trainer before landing on the injured list Thursday with right forearm fatigue. The Giants haven't announced a timeline for the 28-year-old's return, but he's now likely to spend far more time on the injured list than the 15-day minimum.

Lands on IL
The Giants placed Butto on the 15-day injured list Thursday with right forearm fatigue, Alex Pavlovic of NBC Sports Bay Area reports.
Analysis
Butto made an early exit from his appearance against the Padres on Wednesday due to a forearm issue, and he'll now spend at least the next couple of weeks on the injured list getting his forearm back to full strength. Blade Tidwell will come up from Triple-A Sacramento to take Butto's place in the bullpen.

Dealing with arm tightness
Butto was removed during the eighth inning of the Giants' 7-1 loss to the Padres on Wednesday due to right arm tightness, Justice delos Santos of The San Jose Mercury News reports.
Analysis
Butto was brought in for the eighth to keep the Giants' deficit at two runs, but he recorded just one out while allowing four runs on three hits and four walks, tossing 28 pitches (eight strikes) before being pulled. The Giants should have an update over the next couple of days once Butto undergoes some tests on his arm.
