ST. LOUIS (AP) — Andrew Luck threw his first touchdown pass of the preseason, helping the Indianapolis Colts get off to a fast start in a 24-14 preseason victory over the St. Louis Rams on Saturday night. Adam Vinatieri had a big day for the Colts (1-2), hitting field goals on the first and last possessions of the half, plus his successful onside kick led to Andre Johnson's 32-yard reception for a 10-0 lead midway through the first quarter. Starters for both teams played the first half and some went even deeper before a sparse crowd in the Rams' first home game of the preseason.
