"After consultation with the Team USA medical staff and officials, it was determined that he should return to Winnipeg as a precaution due to his previous injury history," Jets general manager Kevin Cheveldayoff said Wednesday in a statement. "Jacob flew to Winnipeg this past weekend and met with team doctors for a series of tests which revealed he had sustained a mild neck strain.
"This will not affect Jacob's off-season training or preparation for next season's training camp in any way."
Trouba missed over a month of action with the Jets this past season due to a neck injury. He had 29 points (10 goals, 19 assists) over 65 games in his rookie campaign.
In four games with the U.S., the 20-year-old blue-liner had three points (2-1) and averaged over 23 minutes of ice time.
