The Seattle Seahawks had a couple of wide receivers leave the Week 1 contest against the Indianapolis Colts early after sustaining hits to the head. Rookie wide receiver Dee Eskridge and Penny Hart are both now in the NFL’s mandated concussion protocol.

Coach Pete Carroll is unsure how long it will be for either player to return.

“It’s going to take a couple of days to get it done,” Carroll said during his Monday afternoon press conference. “They’re not the same, they’re individual cases and we’ll treat them, of course, individually, but there’s a timeframe sequence they have to follow to make it back.

“So nothing to make a prediction about right now other than we’ll see what happens.”

The Seahawks are set to face the Titans in Seattle’s home opener on Sunday and could very well be without both wide receivers.

Tuesday is a player off day, but Carroll should have some additional information on Wednesday before practice.
