Boss was USL-2 goalkeeper of the year in 2008, with Charlotte.

Sounders FC has signed goalkeeper Terry Boss, who played in MLS last season for the New York Red Bulls.

Boss, 27, was United Soccer Leagues-2 Goalkeeper of the Year in 2008, playing for Charlotte. He was signed by the Red Bulls in September and waived last month.

Boss has been training with Sounders FC since early June. Brother Kevin Boss is a tight end for the New York Giants.

“I was aware of Boss while he was playing in USL-2 with the Charlotte Eagles,” said Sounders FC coach Sigi Schmid in a statement released by the team. “He’s got good size, good range, and he works very hard. He had an injury setback last year, but he’s looked very sharp in his training with us. “

Boss led USL-2 in wins (11) and shutouts (9) in 2008, helping Charlotte reach the league title game. After signing with New York, he played in three reserve-team games before sustaining a torn posterior cruciate ligament.

Injury update

Steve Zakuani and Sebastien Le Toux, each recovering from ankle injuries, missed training Friday at Qwest Field.

“Seba’s probably a little further along than Zakuani at this stage,” Schmid said.

Zakuani injured his ankle in Thursday’s practice, while Le Toux is recovering from an injury suffered in the second half last Saturday against New York.
