If that test is also positive, Stroud would be suspended.

Coach Jack Del Rio said Wednesday that Garrard has a high ankle sprain, meaning he has ligament damage and will sit out road games against Tampa Bay and New Orleans. "It's more likely to be three or four [games], somewhere in that window," Del Rio said. "I don't think it's likely to think he'll be back any sooner than that." Del Rio said Quinn Gray will make his first career start against the Buccaneers on Sunday. The Jaguars also planned to work out Doug Johnson, Drew Henson and Todd Bouman later Wednesday.
