Seattle Seahawks cornerback Bryon Maxwell has a "first-degree hamstring injury" that he suffered in a 27-7 win over the Dallas Cowboys on Sunday, head coach Pete Carroll said in a press conference on Monday.

Maxwell is a backup cornerback and a special teams standout who missed the season opener with a shoulder injury. Just 24 hours after the injury, the team is still in the dark about how severe the hamstring injury may be.

"We have to wait and see how it works out," Carroll said. "It might not be that serious, but we don't know."

Maxwell has mainly played on special teams this year. He was selected in the sixth round of the 2011 NFL Draft out of Clemson. Hamstring injuries can be tricky to come back from, so it wouldn't be surprising to see Maxwell miss the Seahawks' Week 3 game against the Packers next Monday.
