Aaron Corp says he is improving and could be back as soon as next week from a cracked fibula in his left leg. He was expected to miss as much as three weeks.

Corp, who was fitted with a brace, has said he is in the training room as often as possible and told the Orange County Register his leg is "definitely improving." Corp may be trying to push his return as true freshman Matt Barkley continues to work as the No. 1 quarterback in practice.

Barkley was intercepted three times in Thursday's morning practice, but rebounded to have on turnovers in the afternoon.

"He came right back out here and cranked it up," coach Pete Carroll told reporters.
