Giants' Madison Bumgarner reveals how he injured his shoulder in dirt bike accident

"I realize this was definitely not the most responsible decision," Madison Bumgarner said

On Friday we learned Giants ace Madison Bumgarner will miss an undisclosed length of time after suffering a shoulder injury in a dirt bike accident in Colorado. He was hurt during an off-day prior to a series against the Rockies in Coors Field.

With his left arm on a sling, Bumgarner spoke to reporters Monday for the first time since the accident, though he did not reveal a timetable for his return. He did, however, personally apologize to each of his teammates.

Bumgarner says he was riding with two relatives in the mountains in Colorado on a rented bike. Almost back to the truck when he crashed.

Bumgarner said he fell off rented Honda riding on mostly dirt. "It wasn't quite as groomed as our dirt infield."

Bumgarner said he's been riding bikes his whole life without issue. "I realize this was definitely not the most responsible decision."

Here is video of Bumgarner talking about the bike accident:

Early estimates peg Bumgarner's absence at anywhere from a few weeks to a few months. Given the nature of the injury -- elbow are easily fixed, relatively speaking, but that is not true with shoulders -- you can be sure San Francisco is going to play it safe with their franchise pitcher.

Bumgarner, 27, had a 3.00 ERA (131 ERA+) with 28 strikeouts in four starts and 27 innings before the injury. He threw at least 200 innings every season since 2011, though obviously that streak will end this year.
