As fantasy teams across the nation crumbled in Week 1, football’s greatest current quarterback (yeah, that’s right) sat down for the first time in his NFL career, following a third procedure on his neck that may have ended his season. But before that, Peyton Manning apparently flew to Europe for an experimental stem cell treatment, according to Fox Sports.

Manning had surgery in May to correct a bulging disc in his neck, but it didn’t solve his problems. Prior to a third surgery in September, he took a private plane to an unknown hospital in an unnamed country, Fox’s Jay Glazer reported in a pregame show Sunday (clip below). The procedure is not available in the United States.

In an email, a Colts spokesman said the team's only comment was head coach Jim Caldwell's "no comment" during a Monday press conference. Caldwell said the team would not discuss Manning's medical issues.
