London, England - If Ryan Tannehill's status as Miami's quarterback was questioned this week, he came up with some answers for head coach Joe Philbin as the Dolphins rolled to a 38-14 victory over the Oakland Raiders Sunday at Wembley Stadium.

Philbin wouldn't officially commit to Tannehill as the team's starter during the week, as the Dolphins (2-2) followed up a stirring season-opening win against New England with subpar efforts in losses to Buffalo and Kansas City.

Tannehill's performance on Sunday should quiet any rumors of backup Matt Moore taking over. Miami's first-round pick in 2012 completed 14 straight passes at one point Sunday, finishing the contest 23-of-31 for 278 yards with a pair of touchdowns and an interception on a deflected pass.

Lamar Miller ran for 64 yards with two touchdowns and the Miami defense was brilliant after allowing a touchdown on Oakland's first series.

Raiders rookie quarterback Derek Carr completed 16-of-25 passes for 146 yards with a touchdown and an interception before exiting the contest in the third quarter with a knee injury.

Matt McGloin took over and threw for 129 yards with a touchdown and two picks as the Raiders (0-4) suffered their 10th straight defeat dating back to last year.

Oakland is winless after four games for the first time since an 0-5 start in 2006, and head coach Dennis Allen's job security will likely be a topic of discussion in the Bay Area on the team's upcoming bye week.
