Smith last played in the NFL in 2009 as a member of the Tampa Bay Buccaneers. He was demoted to the Buccaneers practice squad during the preseason this year and was later cut from the 53-man roster. Smith also spent time on the Miami Dolphins practice squad before working out for the Browns.
Smith is mostly recognized as a return specialist after he returning nearly 70 kicks for 2,000 yards in his two seasons with Tampa Bay. Smith is officially listed as a running back, but has had only 12 attempts through what will be his third season when he comes to Cleveland.
Erik King has been in the NFL a little longer and has played for a number of different teams. King has been a bit of a journeyman but did beat out fellow free agent Jon Wade for a chance to join the Browns team after cornerback Sheldon Brown went down with an injury.
Smith will join the Browns after return specialist Josh Cribbs dislocated four toes in his right foot during last week's game against the Jets. Smith has only one return for a touchdown throughout his career, but was a Pro Bowl selection in 2009.
In an additional piece of news, the Browns placed offensive lineman Billy Yates on IR after he suffered a biceps injury.
