SEATTLE, JAN. 19 -- After saying earlier in the day that he would sit out tonight's game, forward Harvey Grant decided to play against the SuperSonics even though he was still botherd by shin splints in his right leg.

Grant is scheduled to undergo a bone scan Tuesday to determine if anything else is wrong.

Grant, who sat out Friday's 123-99 loss at Portland, entered tonight's game second on the Bullets in scoring with 18.8 points per game.

He said he wants to play against Orlando Monday afternoon at Capital Centre but won't know until then if he can.

Mark Alarie started for Grant at Portland, finishing with 14 points and nine rebounds in 26 minutes. Warm Homecoming

Byron Irvin has no bad things to say about the Trail Blazers. And the team and the Portland fans seemed rather fond of him Friday night as Irvin returned to the city in which he played last season.

"It was a real great place to play," Irvin said. "The fans were great. They packed {the arena} every night. We were winning and went to the championship so that made it even more special, being my rookie year."

But Irvin was sent to Sacramento in the offseason trade that brought Danny Ainge to Portland.

Portland "was a team where I just had to wait and try to look forward to being part of the team," said Irvin, who received a warm round of applause when introduced in Portland Friday. "I thought I was going to be here for a little while, but the trade thing happened. I was kind of disappointed but I knew it was going to be an opportunity for me to go somewhere else and do some things."

That opportunity lasted about two months before he was dealt to the Bullets for Steve Colter. Tough Travel Schedule

Some Bullets were grumbling about the 1 p.m. start for Monday's game on the Martin Luther King holiday after a cross-country flight. In fact, a few players were going to take redeye flights after the game tonight to get home as soon as possible. Kemp, Numbers Growing

Seattle's Shawn Kemp fairly scares people with his potential. The 20-year-old has stepped in at power forward full-time since Xavier McDaniel was traded to Phoenix and is putting up adult numbers, such as the 20-point, 8-rebound, 10-block performance he had Friday against the Lakers.

Kemp attended the University of Kentucky and Trinity Valley (Tex.) Community College, but never played at either before being drafted No. 1 by Seattle last season.

"Last year I had problems getting myself motivated to play some games on the road," said Kemp. "The last time I had played, I played 25 games in high school. Playing this many games, you just really have to get comfortable every night."
