Smith (concussion) didn't participate in Indianapolis' practice Wednesday, Mike Chappell of Fox 59 News Indianapolis reports.
Smith sustained a concussion during the Week 14 loss to the Jaguars and will have to clear the league's concussion protocol before he's eligible to return. If the 29-year-old ends up being unable to play Sunday versus the Seahawks, Jalen Travis would likely start at right tackle in his place.
