Poll: Is Mathews' health a concern?

UDPATE: Our poll issues have been resolved. Thanks for your patience. Oh, and please, take the poll.

The fact that Ryan Mathews was significantly injured on his first carry of the preseason was not a great sign for the San Diego Chargers.

Expected to be the team's workhorse, Mathews suffered a broken clavicle in San Diego's first preseason game. There's some chance he returns for the Chargers' season opener -- Sept. 10 at Oakland on ESPN’s “Monday Night Football” -- but he could also miss a couple of games.

Do you think this injury is a sign that Mathews, who has dealt with durability issues since his college days, will not be able to stay healthy and be the primary back the Chargers want him to be? Or do you think this is an isolated incident and there are no long-term concerns for more injuries this season?

Please take our poll and express the reason for your vote in the comment section below. We will review the poll results Wednesday.
