The Seattle Seahawks will be without rookie wide receiver Jaxon Smith-Njigba for three-to-four weeks after he has surgery to repair a broken bone in his wrist.

Smith-Njigba traveled to Philadelphia on Tuesday for the surgery, according to Pete Carroll.

"He's got a slight fracture that we just want to make sure we do the right thing to ensure that he gets back as soon as possible and as safe as possible," Carroll said. "We're going to be optimistic about it. Three, four weeks, we'll see what happens. We don't know yet."

The Seahawks open the season on Sept. 10 against the Los Angeles Rams in Seattle. Asked if Smith-Njigba could be back by then, Carroll said, "We're staying optimistic. We'll see what happens."
