West Indian opener Chris Gayle is in doubt for Wednesday's tri-series match against Pakistan in Brisbane because of a shoulder injury. The left-handed batsman inflamed tendons in his right shoulder throwing a ball from the outfield during Australia's 116-run victory on Friday at the Melbourne Cricket Ground. On a positive note, left-arm paceman Pedro Collins has fully recovered from a thigh strain and will be a welcome addition to the injury-hit squad at the Gabba ground in Brisbane.
