NBA: Portland signs coach Terry Stotts to contract extension

Fresh off their surprising run in the playoffs, the Portland Trail Blazers have signed head coach Terry Stotts to a multiyear contract extension.

Stotts led the Blazers to a 54-28 regular-season record, for the team's biggest improvement in team history. Portland made the playoffs for the first time since 2011, dispatching the Houston Rockets in six games, before falling to the San Antonio Spurs in five games in the Western Conference semifinals.

Stotts has an 87-77 record in two seasons with the Blazers, after serving as an assistant with the Dallas Mavericks for four seasons.

The terms of the deal were not disclosed.

Clippers' Rivers fined

The NBA fined Clippers head coach Doc Rivers $25,000 on Thursday for publicly criticizing the officiating in Los Angeles' 105-104 loss to the Oklahoma City Thunder earlier this week.

Rivers was livid after the game, saying the Clippers were "robbed."

The Clippers believed the Thunder's Reggie Jackson had knocked the ball out of bounds with 11.3 seconds remaining, but officials ruled it Oklahoma City ball. After going to replay, the call stood, and the Thunder rallied to win the game.

Parker's injury mild

The San Antonio Spurs say point guard Tony Parker has a Grade 1 strain of his left hamstring and is listed as day-to-day.

Parker had an MRI exam on Thursday, one day after leaving Game 5 of the Western Conference semifinals against Portland with the injury. A Grade 1 strain is considered the least severe of the three grades, so the Spurs appear to have avoided what would have been a devastating injury to their best player.

Parker had a Grade 2 strain in the NBA Finals last season, but was able to play through the injury.

Nets guard D-Will ponders surgery

Brooklyn Nets guard Deron Williams plans to have an MRI on his ankles, which have slowed him the last two seasons, and he may end up surgically repairing them in hopes of relocating his game and his confidence.

"It just took a beating on me," the former Utah Jazz star said. "Just couldn't do what I wanted to, can't finish the way I want to finish. You just start thinking about things. So that was just the main thing. Confidence-wise, it's hard to get back to where I was."

Meantime, the Nets face a decision on Paul Pierce, who will be a free agent and showed he can still provide a team with scoring punch at 36.

Kevin Garnett remains a strong defender and team leader, but averaged a career-low 6.5 points in 54 games, missing a large chunk of the season with back spasms and playing just 20.5 minutes per game as coach Jason Kidd tried to keep him fresh for the playoffs.
