INDIANAPOLIS (AP) Andrew Luck's most recent snap with the starting offense came in January.

Adam Vinatieri, the NFL's career scoring leader, missed Indy's first two preseason games with an injured knee. All-Pro left guard Quenton Nelson missed all of last week with a sore ankle and starting defensive end Jabaal Sheard hasn't practiced since early August because of a problematic knee.

So far, the Colts have managed to adapt. But with the Sept. 8 season opener against the Los Angeles Chargers quickly approaching, coach Frank Reich needs answers.
