INDIANAPOLIS -- Linebacker Marcus Smith, the Eagles’ first-round draft pick who didn’t play a snap in last week’s season opener, is inactive for tonight’s game against the Colts.

Running back Chris Polk, who missed the entire preseason and last week’s game with a hamstring injury, will be dressed tonight. So will both of the potential replacements for left guard Evan Mathis, Dennis Kelly and newly signed Wade Smith. It is unclear which of those will start.

Emmanuel Acho, who was signed off the practice squad last week, will dress. He will be one of eight linebackers in uniform. Smith is the odd man out.

Last week, Smith was sidelined because defensive coordinator Bill Davis decided to have Brandon Graham play at both outside linebacker spots. With Smith active, the Eagles had only two reserve offensive linemen available. Both were pressed into service due to injuries.

The situation is the same tonight. Either Kelly or Smith will be one backup lineman. David Molk will back up center Jason Kelce.
