DAVIE, Fla. -- Miami Dolphins running back Matt Breida has been ruled out for Sunday's game against the Arizona Cardinals with a hamstring injury, another blow to the team's banged-up backfield.
With Myles Gaskin placed on injured reserve earlier this week with a knee injury, the Dolphins will have to lean on Jordan Howard -- a disappointing free-agent signing -- to step up in a prominent role. Howard has been a healthy scratch over the past three games as he fell behind Gaskin and Breida in the rotation, and Sunday he could be propped into a starting role.
