Pete Carroll unsure of Brandon Browner, Percy Harvin fitness

Seattle Seahawks head coach Pete Carroll has admitted that he does not know if injured duo Brandon Browner and Percy Harvin will be fit for their week 16 clash with the Arizona Cardinals.

The Seahawks can secure the number one seed in the NFC playoffs with a victory on Sunday but could be without Browner, who has a groin injury, and Harvin who has suffered a setback in his recovery from hip surgery.

"We'll find out on Wednesday. [Browner's] got two days of running here to see how he does and we'll see what happens. We don't know," Carroll told reporters.

Carroll's side are 12-2 in their season with two games left to play.
