CINCINNATI -- It appears rookie right-handed pitcher Jon Moscot will be done for the season with "significant damage" in his left shoulder.

Reds manager Bryan Price announced on Thursday that Moscot (1-1, 4.63) will need surgery to repair a dislocated left shoulder. Moscot experienced the injury while tagging Tigers' center fielder Anthony Gose at second base in the first inning on Monday.

"It would be optimistic to think that he'll be back pitching [this season]," Price said. "That being said, he's a young man with a great work ethic so I don't know the exact time table. It's certainly longer than it would be if the injury didn't need the surgical repair so the exact amount of time I'm not 100 percent sure. I don't think it's probable that he will be pitching by the end of the year but we'll see."

Moscot, who was put on the 15-day disabled list on Tuesday, suffered the injury in only his third career start. The 23-year-old recorded a loss in his Major League debut on June 5 against the Padres, giving up four earned runs on four hits and three walks in five innings pitched. However, he bounced back in his second start on June 10 against the Phillies, giving up only two earned runs in six innings for his first career win.

"He certainly will be ready for 2016," Price said. "The good news is it's something that he has to do to create the stability in the shoulder and may as well do it now, and get it taken care of and not have to worry about it going forward when his rehab is finished."

A replacement for Moscot in the rotation has yet to be announced by Price. Moscot's next start was slated for Saturday against the Marlins.

Moscot is the Reds' third starting pitcher currently on the DL, including fellow rookie Raisel Iglesias and veteran Homer Bailey. Iglesias is expected to return from a left oblique strain, while Bailey has been shut down for the season after Tommy John surgery on May 8.
