NEW YORK -- Timberwolves backup point guard J.J. Barea returned to action in Brooklyn on Monday, approved to play by the NBA one night after he got hit hard in the head and sustained what the team called "concussion-like symptoms" during a game in Toronto.

The NBA informed him a league-appointed doctor had reviewed tests he underwent and ultimately passed Sunday night and Monday -- and cleared him to play not long after it also announced he is one of the first two players warned under a new anti-flopping policy.

Barea was warned for flailing his arms and staggering backward after Sacramento's Jimmer Fredette struck him with a forearm while driving with the ball Friday. Fredette was called for charging. Barea will be fined $5,000 if the NBA office reviews game film and deems he overacted in an attempt to draw a foul call.

He seemed bemused with the distinction.

"It was a charge, though," he said, grinning. "We won the game. It helped us."

Wolves coach Rick Adelman wasn't much amused.

"I don't know how anybody 1,000 miles away on TV can tell if somebody gets hit or not," Adelman said. "The play they're talking about, the guy hit him in the face and got called for a foul. I don't understand how he can get called for a warning foul. It sounds like maybe they're trying to use his reputation.

"It seems like our officials are supposed to be best in the world. They've very good officials, and they should be able to tell if someone gets hit or if he's faking it."

He's back

Barea underwent some of the same tests Monday he took for his preseason physical examination to test his brain after running and riding an exercise bike. He did as well or better or he wouldn't have been cleared by the NBA to play.

"I feel good," he said before the game.

Assert yourself

Starting shooting guard Brandon Roy didn't take a shot in Sunday's first half and took just three all night against the Raptors. Afterward, he vowed to be more aggressive looking for his own shot. On Monday he took four shots and had six assists by intermission.

"It's going to be a process, and he and everybody else has to understand that," Adelman said. "He has been out a year. He's coming back. ... That's how he has always played. Sometimes he is open and he has to look for his shot. It's just something he'll have to learn. I think he'll figure it out. He's a smart player."

New-look Lexey

Rookie guard Alexey Shved's flowing hair and headband were gone Monday night, history after he got a haircut in New York City after breakfast.

"C'mon guys, it's not so big news," he said surrounded by reporters before the game. "I want change something, I stay a long time with long hair."
