UCLA assistant coach DeShaun Foster is leaving Chip Kelly’s staff to join the Las Vegas Raiders as the organization’s next running backs coach.

The move was reported several days ago. Foster confirmed his departure in a tweet on Tuesday, saying goodbye to UCLA fans after seven years on staff.

“UCLA will be missed,” he wrote. “Raider nation, let’s go!!!”

After a standout college career with the Bruins from 1998-2001, Foster was a second-round draft pick of the Carolina Panthers in the 2002 NFL Draft. The former All-American ended his collegiate career second on the all-time touchdowns scored list (44), third on the school’s all-time rushing list (3,194 yds), and fifth on the all-time Bruin scoring list (266 pts).

He spent six seasons in the NFL — five with the Panthers. He ran for 3,570 yards, added another 1,129 yards as a receiver, and scored 16 career touchdowns.

Foster was hired by Kliff Kingsbury in 2016 to be the running backs coach at Texas Tech. A year later, he returned to UCLA to work under former head coach Jim Mora. Chip Kelly retained him when he took over the Bruins.

With the Raiders, Foster nearly reunited with Kingsbury, who was in advanced talks with the organization to become the next offensive coordinator. Contract talks broke down between the two sides and Kingsbury went to Washington instead.

Foster is the fourth assistant to leave Kelly’s staff this offseason, and he’s the third to do so on the offensive side of the football. Kelly has also had to replace his tight ends coach and his quarterbacks coach.
