BO READY TO DO IT:

The Los Angeles Raiders are considering as many as three moves before Sunday's game with the Chargers at San Diego, including the addition of running back Bo Jackson to the active roster.

The Raiders are also expected to activate former all-pro defensive end Howie Long from injured reserve, and they were considering the addition of linebacker Alex Gordon, who was on injured reserve with the Jets before being acquired by the Raiders Monday.

The Raiders currently have one vacancy on the 47-man roster, created by the trade of safety Vann McElroy to the Seattle Seahawks.

Jackson reported to the team Monday, 10 days after his baseball season in Kansas City ended. Activating him is a formality.

The last two seasons, he has played the week he has reported to the Raiders.

He carried 11 times for 85 yards in his first game last year, and 21 times for 70 yards in his 1988 debut. In 1987, his rookie NFL season, Jackson did not play the week he reported.

Long broke a toe at Seattle on Sept. 16 and was expected to miss six weeks. He was able to practice this week and hopes to play against the Chargers.

Gordon is a former starter with the Jets who went on injured reserve with a hamstring pull in training camp. He practiced with the Raiders and could be used on special teams or as a backup.

To activate more than one player, the Raiders must clear roster spots. Candidates for injured reserve include running back Greg Bell (sprained ankle), defensive end Mike Wise (sprained ankle) and linebacker Art Jimerson (neck strain).

WLAF TRYOUTS:

The World League of American Football will sign more than 800 players during a nine-city evaluation tour of North America, league officials said.

The invitation-only camps will start in Montreal on Nov. 3 and end in Los Angeles on Dec. 2. Former NFL, Canadian Football League and college players will be given tryouts.

Each player signed will report to Orlando, Fla., in February for the league's player-allocation draft. The league's first season is expected to begin in March.

NEW CHIEF:

Cornerback Charles Washington of the Kansas City Chiefs was placed on injured reserve because of a sprained ankle. Washington, who played mostly on the special teams, was hurt in Sunday's game with Detroit. To take his place on the roster, the Chiefs re-signed linebacker Rob McGovern, their 10th round draft choice last year. McGovern, who had been waived Oct. 6, led the club in special teams tackles last year with 24.

COWBOY HURT:

The Dallas Cowboys placed seven-year veteran guard Tony Slaton on injured reserve after he strained his lower back. Slaton was injured during practice Wednesday. He started this season's first four games at right guard.

OILERS ADD TOP PICK:

The Houston Oilers' No. 1 draft choice, Lamar Lathon, was activated and will suit up for Sunday's game against New Orleans in the Astrodome.

Lathon had been sidelined since preseason with a shoulder injury.

The Oilers also activated cornerback Dee Thomas to fill out their 47-man roster.

TV BOOMER:

Cincinnati Bengals quarterback Boomer Esiason will make his debut as a television character actor in January on the Home Box Office series, "First and Ten: In Your Face."

He will play an unscrupulous doctor who injects drugs into a star quarterback so he can play in the big game.
