Dallas Mavericks guard J.J. Barea tore his right Achilles tendon in a game Friday against Minnesota, a season-ending setback for a key Mavericks' reserve.

Barea was injured in the second half of the Mavericks' 119-115 victory in Minneapolis. The team said Saturday that Barea was weighing his options for surgery.

The 34-year-old Barea was averaging 10.9 points and a team-high 5.6 assists as a key part of the second unit for Dallas. The injury is likely to mean a significant increase in playing time for rookie Jalen Brunson, a two-time NCAA champion at Villanova and second-round draft pick.

Thunder to retire No. 4

The Thunder will retire Nick Collison's No. 4 in March.

The team made the announcement in a news release on Saturday.

The ceremony will take place when the Thunder hosts the Toronto Raptors on March 20. The crowd favorite's number will be the first the franchise has retired since moving from Seattle to Oklahoma City before the 2008-09 season.

Collison announced his retirement last May after spending all 15 years of his career with the Thunder franchise, which was the Seattle SuperSonics when he was drafted 12th overall in 2003. He appeared in 910 regular season games with 177 starts and posted career averages of 5.9 points, 5.2 rebounds and 1.0 assist in 20.4 minutes per game.

Collison joins Russell Westbrook as the only players to spend the first 10 years of the Thunder era all with the team.

Wade, Rozier exchange jerseys

Dwyane Wade's jersey exchange with Celtics guard Terry Rozier following Thursday's game was pre-planned ... in November.

"Let's (go back to) late November," Wade said before the Heat hosted the Grizzlies on Saturday. "I wake up the next day, and I got a text at 4 in the morning from Terry Rozier. He's like, 'Yo, I'm going to need that jersey.' "

Rozier, a 24-year-old bench player who grew up in Ohio, got what he asked for as Wade handed him his black Heat "Vice Nights" uniform following Miami's 115-99 win over Boston. It marked the first of four meetings this season between the Heat and Celtics.

Rozier said after Thursday's game that "it was mandatory I got his jersey. I wouldn't let nobody else get it."

Wade has already exchanged jerseys with All-Star players like New Orleans' Anthony Davis, Los Angeles' LeBron James, Toronto's Kyle Lowry and Washington's Bradley Beal. Swapping jerseys with an opposing player after each game has become a signature element of Wade's final NBA season.
