Colts quarterback Andrew Luck: 'We've got a lot to improve on'

After squaring their record at 1-1 with a win at Washington, Luck's Colts venture to Philadelphia for another road test.

INDIANAPOLIS — The normal NFL weekly routine means media surrounding the locker of Colts quarterback Andrew Luck on Wednesday.

Luck addressed a variety of topics as the Colts prepared to travel to Philadelphia for a 1 p.m. Sunday kickoff against the reigning Super Bowl champions at Lincoln Financial Field.

It’s a matchup of 1-1 teams after the Colts won 21-9 at Washington while the Eagles lost 27-21 at Tampa Bay.

"I think as a team, we've got a lot to improve on," Luck said.

Numerous subplots include Colts first-year head coach Frank Reich returning to where he served as offensive coordinator the past two seasons. Second-year Eagles quarterback Carson Wentz will make his first season debut in returning from knee surgery that was needed after getting hurt in the 13th game last year.

The Colts have a lengthy list of injured players who will miss the game: LT Anthony Castonzo, TE Jack Doyle, DT/DE Denico Autry, RB Marlon Mack, DT Hassan Ridgeway and CB Quincy Wilson.

Castonzo, Doyle, Autry and Mack are all starters. Castonzo has yet to play this season due to a lingering hamstring injury. Autry will miss his second consecutive start with a sore ankle. Doyle suffered a hip injury but finished the Redskins game. Mack played on a limited snap count and is dealing with foot and hamstring issues.

Safety Clayton Geathers is questionable with knee and elbow injuries.

Le'Raven Clark is expected to make his second consecutive start at left tackle for Castonzo while Joe Haeg, who subbed at left tackle in the season opener, will start a second straight week at right tackle.

The Colts will start Eric Ebron for Doyle and promoted tight end Eric Swoope from the practice squad. Cornerback Lenzy Pipkins was waived to make room for Swoope. Quarterback Phillip Walker was re-signed to the practice squad.

Colts rookie linebacker Darius Leonard generated most of the buzz this week after being named AFC Defensive Player of the Week and Pepsi NFL Rookie of the Week. Credited with an additional tackle assist upon further review, Leonard had 19 total tackles including 15 solos, the most for a Colts rookie since 1994, in the road win over the Redskins.
