WEST Indies's already fragile batting line-up has been weakened further with opener Chris Gayle to miss the final Test in Adelaide after undergoing minor heart surgery in Melbourne.
Gayle, who was forced to retire hurt during last week's second Test in Hobart after experiencing nausea and dizziness due to an irregular heart beat, surprised team officials by undergoing the procedure on Tuesday evening.
After being forced from the field during the opening hour of last week's match at Bellerive Oval, Gayle announced he would undergo minor corrective surgery at the completion of the Australia tour.
But the 26-year-old opted to enter hospital as soon as the squad returned to the mainland en route to Adelaide.
He spent Tuesday night under observation in Melbourne and will remain in the Victorian capital before returning to the Caribbean next week.
Despite a modest 103 runs from four Test innings in the series against Australia, Gayle remains one of the struggling tourists' few genuine world-class batsmen and represents a significant loss.
Gayle's absence comes just days after underachieving middle-order batsman Marlon Samuels was sent home to receive further treatment for a knee injury.
It leaves ailing West Indies with a bare minimum touring party of 13 fit players and ensures deposed opener Wavell Hinds will return, after fracturing his left little finger, to partner Devon Smith at the top of the order.
And all-rounder Dwayne Smith, who made a significant contribution as a substitute fielder during the Hobart Test, will slot into Samuels' vacant middle-order berth.
The biggest headache facing the overworked West Indies's brains trust entering the dead-rubber Test which begins tomorrow is who will occupy the role of part-time spinner with Gayle and Samuels absent.
On a flat Adelaide pitch which is expected to provide its traditional encouragement to batsmen, West Indies faces the nightmare prospect of tackling the strong Australia batting line-up with a reliance on a couple of barely part-time tweakers.
Captain Shivnarine Chanderpaul (eight wickets from 90 Tests) and his deputy Ramnaresh Sarwan (20 from 57) will share the responsibility of slow-bowling duties as well as lifting the team's appalling over-rate.
So desperately short of a competent slow bowler are West Indies, it is not inconceivable that 36-year-old batting hero Brian Lara may cap what is expected to be his final Test in Australia with a chance to capture his first Test wicket.
Certainly in the absence of Gayle and Samuels, Lara will carry an even greater burden as the mainstay of his team's batting.
Despite failing to reach 50 in any of his six Test innings (for the World XI and West Indies) in Australia this season, Lara's arch-rival and close friend Shane Warne believes the brilliant left-hander is not a spent force at international level.
Warne predicted Lara was overdue for one of his trademark huge hundreds and said he expected the enigmatic Trinidadian to return to Australia when West Indies tour here again in 2009-10.
"I think he'll be back," Warne said yesterday.
"It depends on whether the West Indies can unearth three or four other batsmen that can take his place."
