The Oklahoma City Thunder will retire Nick Collison's No. 4 jersey on March 20, the team announced on Saturday.

Nick Collison spent his entire NBA career with the Thunder. He was with the organization when they were still the Seattle SuperSonics as well.

Collison was the 12th overall pick in the 2003 NBA Draft out of the University of Kansas.

In 910 career games with the Thunder, Nick Collison averaged 5.9 points, 5.2 rebounds and 1.0 assist per game while shooting 53.4 percent from the field and 72.3 percent from the free-throw line.

Collison is third in franchise history in games played, trailing only Gary Payton and Fred Brown. He is ninth in minutes played, fourth in rebounds and sixth in blocks.

Collison was always a fan favorite in OKC and deserves to have his number retired. He was never the most talented player, but Collison's rugged style of play and the effort he showed on a nightly basis is why the fans in Oklahoma City loved him.

Thunder star point guard Russell Westbrook has said multiple times that Collison is his favorite teammate of all-time. Westbrook will most likely participate in the jersey retirement ceremony in some way or fashion. The Thunder take on the Toronto Raptors on March 20.
