Here`s the line score on Bo Jackson`s return Sunday to the city where he plays baseball: 3 runs, 1 hit and more errors than anyone thought possible.

Unfortunately, the sport was football, and Jackson`s highly publicized homecoming as a member of the Los Angeles Raiders turned into one of the longest afternoons of the season before the Kansas City Chiefs won 16-10.

The 63,834 fans in Arrowhead Stadium, largest crowd to attend a Chiefs`

home game in December since 1973, got to see Jackson run with the football only three times and catch one pass before he left in the second quarter with a sprained ankle, an injury practically no one saw happen.

''It`s very frustrating,'' said Jackson, who gained one yard on the ground and four in the air. ''I came here to have a good time. The little time I was on the field, I felt great. I haven`t left a game like this since I tore up a shoulder when I was a junior in college.''

Jackson said he twisted his ankle on the game`s first play, when he tried to make a cut on a sweep and was tackled by defensive end Mike Bell for no gain. He aggravated it on the Raiders` second possession in a pileup. Kansas City tackle Bill Maas, who had sacked quarterback Marc Wilson, apparently landed on Jackson.

''I don`t care if it was Bo Jackson or Bo Diddley because I was just trying to get to the quarterback,'' Maas said. ''I don`t know what happened to him, but I didn`t roll on top of him.''

Jackson left the game midway in the first quarter for X-rays, which showed no break. He returned for the start of the second quarter, lost one yard on a pitch play from Wilson and left for good.

Robbed of the main attraction in a game that pitted teams with a combined record of 7-17, the crowd got ugly in what Kansas City linebacker Jack Del Rio labeled ''a tasteless lack of class.''

More than a dozen baseballs rained down on the field from the upper decks at various times, endangering players as well as fans below them and others on the sideline. One Raider threw a baseball back into the stands.

Dozens of banners were strung across the upper decks, with some of the more obscene ones removed by security forces. The majority indicated that Jackson, a budding slugger last season as a Royals rookie outfielder, was a

''T-Raider'' playing for the Chiefs` most hated rival.

''This game was special to me,'' Jackson said. ''Not just for me, but for other people, too. To have a city root against you, well, I can`t say it`s nice, but it`s an experience.''

Some of Jackson`s teammates from the Royals were on hand, and third baseman George Brett came from California just to see the homecoming. Football Hall-of-Famer O.J. Simpson came with the Raiders on their chartered airplane. The Chiefs were upset that Jackson caused such a commotion.

''Knowing there would be a big crowd was a big motivator,'' said linebacker Dino Hackett. ''I know two or three times this week I got tingly just thinking about him and all the publicity he was getting.''

''I was really disappointed,'' Del Rio said, referring to the large turnout. ''All we heard all week was come to the game to see Bo and wear your Royal Blue. In the end, it was just another Raider-Chiefs game.''

As such, it was brutal. There was one brawl and a half-dozen individual skirmishes. When Chiefs wide receiver Carlos Carson caught a 67-yard touchdown pass from Bill Kenney, he stopped his sprint at the 3-yard line to turn around and taunt pursuers before stepping across the goal line.

Carson`s touchdown was the highlight for the Chiefs` offense. Their biggest gainer on the ground was a 16-yard scramble by punter Kelly Goodburn. There were 24 penalties; the Raiders had 14 for 140 yards, almost 60 more than they gained with their ground game after Jackson`s exit. There were seven fumbles and four interceptions.

The Raiders gained 400 yards but scored only 10 points.

''This game was small consolation for the season,'' Del Rio said. ''I mean, we`ve won three times and we`ve just had a terrible year. I`m not going to go home and drink champagne.''

At the very least, nobody cried ''let`s play two.''
