OTTAWA -- With Chris Bosh letting his hamstring heal, first-year Raptor Amir Johnson is logging a lot of court time at power forward this camp. The fact that he hasn't lost a step the whole week or even slowed down caught the attention of head coach Jay Triano, who was a little concerned it might be too much work.

Apparently, the thought never crossed Johnson's mind after what he went through as a youngster on a veteran-laden Detroit Pistons team the past few seasons.

"When you got the veterans, they pretty much had you at the front of the (drill) line every time," Johnson said of his days in the Motor City. "You pretty much had to do all the running for the vets so I'm pretty much used to it. I used to run track myself so I'm not afraid of a little bit of running."

Study up boys

To hear Bosh tell it, attention to detail, particularly positioning on the floor is going to be key for the Raptors this year.

"We have the opportunity to spread the court a lot this year, but we have to know where our spots have to be," Bosh said. "Each spot has to be filled by one of the five guys. I know if Hedo and Bargnani are in the game, I'm going to have to roll and be inside because that's where my advantage is. Everyone has to know their role and know their spots and work well together."

Breaking camp

Today's Raptors scrimmage, which will bring to a close the Ottawa portion of training camp, is going to be rather informal. Triano expects he'll just let assistants Marc Iavaroni and Alex English draft teams. With only 13 players available, he expects players will be flip-flopping onto both teams to keep the playing time equal.

Board expands replay

NEW YORK -- NBA referees will be able to use instant replay on shot-clock and out-of-bounds calls this season after the league's board of governors approved the expanded use.

Referees will be permitted to check replay to see if the 24-second clock expired before a successful shot or a foul.

They can also consult video during the last two minutes of regulation and any overtime period to determine which player last touched the ball prior to it going out of bounds.

Return of Agent Zero

RICHMOND, Va. -- Gilbert Arenas took part in five-on-five halfcourt drills at Washington Wizards practice after sitting out scrimmages the previous two days.

Wizards first-year coach Flip Saunders says the oft-injured Arenas has taken part in just about everything during training camp but a dislocated finger sidelined him for the scrimmages.

Arenas dislocated the middle finger on his left hand in a pickup game before training camp began, then aggravated it this week. Saunders says it could be an ongoing issue all season.

Surgery for Walker

BOSTON -- Boston Celtics forward Bill Walker underwent successful right knee arthroscopic surgery.

The surgery at the New England Baptist Hospital was aimed at repairing a meniscus tear Walker suffered on the first day of training camp. The team said no timetable has been set for his return.
