Tukwila - The younger brother of English striker Wayne Rooney is currently on trial with the Seattle Sounders FC in the MLS.
The team confirms that John Rooney, 19, is practicing with the club.
He joined the team for its training session on Tuesday, but has not yet signed for the Sounders.
If he were to join the league, Rooney would have to go through the MLS Superdraft.
Seattle coach Sigi Schmid tells The Seattle Times that Rooney was brought to their attention and, with having a full week of training at home, decided to give him a look, along with some other players.
Rooney has played for Macclesfield Town in England's League Two. He had a trial last year with League Championship team Derby.
