Owings Mills, Md. ? Rookie quarterback Troy Smith will make his first start Sunday when the Baltimore Ravens visit the Seattle Seahawks.

With Kyle Boller missing his second consecutive day of practice due to lingering effects from a concussion, including headaches and sensitivity to light, Ravens coach Brian Billick confirmed Thursday Smith will take his place.

Billick acknowledged that Smith, last year’s Heisman Trophy winner at Ohio State, also may start the season finale against the Pittsburgh Steelers due to Boller’s injury.
