Boone (chest) is inactive for Sunday's game against Philadelphia, Darren Urban of the Cardinals' official site reports.
Boone will miss his second straight game after straining his pectoral muscle. He did show improvement in practice this week, so Boone could be trending toward a return to action in Week 6 against the Buccaneers. Earl Watford will draw the start at left guard in Boone's stead.
