XavierSilas (face) had successful surgery last week to repair "several sinus fractures."
Silas was injured during a summer league game where he took an elbow from a teammate and also suffered a concussion as well. He had facial surgery to repair the issue and it's not yet known how long he'll be forced to sit on the sidelines.
Sixers signed G XavierSilas for the remainder of the regular season.
Silas impressed the Sixers' brass with a strong training camp, but there just wasn't enough room for him on the roster. He'll likely see minutes over the final two games with the team now resting/tanking ahead of the playoffs.
