Knicks sign guard Chris Smith

Free agent guard Chris Smith has signed with the New York Knicks, uniting him with older brother J.R. Smith.

Smith's agent, Marc Cornstein, wouldn't disclose terms of the agreement -- it's likely nonguaranteed -- but he called the opportunity "a dream come true for Chris."

"We are very excited about him joining the Knicks and look forward to him getting a real opportunity to contribute," Cornstein told ESPNNewYork.com.

"He's now going to have to work extremely hard and establish himself as part of this veteran team."

On Wednesday, J.R. tweeted a photo of Chris signing his contract.

Chris Smith, a point guard out of Louisville, played for the Knicks' summer league team in Las Vegas.

A source familiar with the situation said the Knicks acquired Smith so they could assign his rights to their D-League team, the Erie BayHawks.

"The D-League is an option, as it is for all rookies," Cornstein said.
