Officials told NBC that it occurred on Spruce Avenue and Sigel is currently in surgery.
No other details were provided.
This is not the first time that the rapper has sustained such an injury. In May of 2006, Sigel was shot twice in his home during an attempted robbery. He was also arrested in 2002 on a federal weapons charge, followed by a charge of attempted murder in 2003. He was acquitted of the later charge, but served a year in prison for the former.
In 2012, Sigel returned to prison to serve a 24 month sentence after being found guilty of tax evasion and narcotics possession. He was released this past August and was reportedly staying at a halfway house in Philadelphia to serve out the remainder of his sentence.
