Indianapolis Colts Lacey was signed by the
Indianapolis Colts as an undrafted free agent in 2009 and made the initial 53-man roster. He had his first career interception and first touchdown on the same play. The play was made on
Marc Bulger of the
St. Louis Rams, and returned it 35 yards for a touchdown. At this time, he also received his first celebration penalty. Lacey was fined $10,000 and penalized 15 yards for sliding into the end zone and making an official’s safe signal. The following day, the cornerback told reporters the celebration was planned for when and if he scored. “If I would have known ahead of time, I probably wouldn’t have done it, but I didn’t know. I’ll try to get into the end zone and spice it up again.” Within one week, the fine was rescinded. Lacey shared the field with former high school teammate
Melvin Bullitt. When asked why he signed with the Colts, Lacey answered, “I had a friend that [sic] I played high school football with who was already on the team... He took the same path as me as a free agent. So I knew they would give a free agent a good look, a good shot, a fair chance.” With a couple of Colts injuries early in the season, Lacey was able to start in a few games. Also, later, in week 15 of the 2009-10 season, Lacey intercepted
David Garrard, sealing the victory to put the Colts at 14-0. In 2010, Lacey appeared in 11 games, starting seven. His season highlight was a 44-yard interception return. He suffered an ankle injury mid-season and missed three games. He returned in the week-9 loss to Philadelphia, establishing himself as a starter for the rest of the season.
