Philadelphia Union have reportedly signed former U.S. youth international Sheanon Williams, and he is expected to be available to play Wednesday night against Chivas Guadalajara.

Williams played this season with the Harrisburg City Islanders, a USL-2 affiliate of Philadelphia Union, thanks largely to the intercession of Union assistant coach John Hackworth, who worked with Williams as a youth international. The Union have not yet announced the signing, which was reported by the Boston Globe earlier today. The Union confirmed it later on their web site.

Williams has played both right back and striker, and he could see time at either or both for the Union, who lack depth on defense and potentially at forward. He is 20 years old and was an all-American in high school. After playing a year for the University of North Carolina, Williams left school early for trials with European teams such as Wolfsburg in Germany but returned stateside without a contract. He recently had trials with the New  York Red Bulls and New England Revolution before signing with the Union.

The Union have an open roster spot and likely do not have to cut anyone to make room for Williams on the 24-man roster.
