The U.S. U-20 midfielder had his leg broken during Liverpool's U-21 victory over West Brom earlier this week, and the procedure to correct the injury went according to plan.
Pelosi, who had been named to Liverpool's UEFA Europa League squad and was prevented from joining the U.S. U-20s for the ongoing CONCACAF championship, suffered the injury during Liverpool's U-21 victory over West Brom on Monday.
Pelosi, 18, was the victim of a hard challenge and one that broke his tibia. Nigel Jones, the Liverpool academy doctor, assured that the surgery to correct the injury was a success and that Pelosi is on the road to recovery.
"Marc sustained a nasty fracture to the main bone in his leg - his tibia - and he had surgery on Monday evening to put that back into a good position," Jones told LiverpoolFC.com. "Everything went well with the surgery, and we'll work hard to make sure he gets back as soon as possible."
Pelosi is the second key U.S. U-20 player to suffer a broken leg this season after Birmingham City defender Will Packwood suffered the same fate in an FA Cup match against Leeds United in January.
