Lawson headed the West Indies bowling averages against Australia

The young Jamaican has been reported to the International Cricket Council after the umpires expressed doubts about his action during the fourth Test against Australia in Antigua.

"I've told him what remedial action we will take, cautioned him about the hype surrounding the issue and ribbing he will receive.

"He has to cast that out of his mind and be aware that we are behind him," said WICB president Wes Hall.

Lawson has emerged as a bowler with the potential to spearhead the West Indies seam attack for many years to come and returned his best Test figures of 7-78 earlier in the game.

He will now spend six weeks working with bowling advisers, but will be allowed to continue playing during that period.

The 21-year-old has been named in the West Indies squad for seven one-day internationals, the first of which takes place in Jamaica on 17 May, although he is suffering from a back strain.

Hall, a former fast bowler who took 192 wickets in 48 Tests, believes there is too much pressure on youngsters to strive for extra speed at all costs.

Pakistan's Shoaib Akhtar bowled a 100mph delivery last year, but both he and rival Brett Lee of Australia have been reported in the past because of doubts about their actions.

"It is quite possible with all the hype surrounding 100 mph that youngsters will strive and go beyond the bounds. We need to look at that," said Hall.
