LONDON (AP) - Dallas Cowboys quarterback Tony Romo has practiced for the first time since arriving in London, taking part in Thursday's drills.
Romo, who missed last Sunday's 28-17 loss to the Arizona Cardinals with his third back injury in the last 18 months, arrived with the team on Tuesday but skipped Wednesday's practice.
Dallas coach Jason Garrett says Romo is still not assured of starting on Sunday, when the Cowboys (6-3) play the Jacksonville Jaguars (1-8) at Wembley Stadium.
Garrett says "he has to be functional."
Romo has fractures in two small bones in his back. The injury is unrelated to a herniated disk sustained last year and to offseason surgery to remove a cyst earlier in 2013.
