Clarets agree Richards deal
The 28-year-old Jamaica international, who used to play for New York Red Bulls, will join the Clarets on January 1 when his deal with the MLS side expires.
Manager Eddie Howe said: "We are delighted to have signed Dane, who is a player we have been tracking for a while.
"I watched him at New York, where he played for a number of years and he is someone who has all the attributes we are looking for to add to our squad.
"He is quick and direct, has a real turn of pace and I think he will be joining us at a good time in January, hopefully to give us a push in the second half of the season.
"He has good international experience, he is a good age and we're looking forward to adding him to the squad."
