On April 28, 2004, Adams signed with the San Francisco 49ers as a undrafted free agent.  Adams was waived by San Francisco on September 4, 2004.  Adams signed to the 49ers practice squad on September 6, 2004.  Adams was elevated to the San Francisco 49ers active roster on November 13, 2004.  Adams spent three seasons in San Francisco, starting in 18 games and recording five interceptions. Following the 2006 season, Adams left San Francisco and signed with the Cleveland Browns.
Adams was signed by the Cleveland Browns as a free agent on April 2, 2007.  Adams went on to start in 32 games over a five-year period with the team.

On March 15, 2012, Adams signed with the Denver Broncos as an unrestricted free agent.  After joining the team, Adams chose jersey No. 20—which was previously worn by legendary safety Brian Dawkins before he retired during the 2012 offseason. “Hopefully I make him (Dawkins) proud wearing his number,” Adams stated in May.  Heading into the 2012 season, Adams was expected to be one of Denver's two starting safeties this season. Before the start of Super Bowl XLVIII, Adams vowed to walk about 12 miles (19 km) from MetLife Stadium back to his childhood home if the Broncos were to win the Championship.  He was released by the Broncos early in May 2014.
On March 10, 2015, Adams re-signed with the Colts on a two-year contract.  Adams was named to his second-consecutive Pro Bowl on January 25, 2016, as a replacement for the injured Kam Chancellor.
