Do-or-die situation for Knights

With Rawalpindi Express Shoaib Akhtar uncertain to play with a knee problem, Kolkata Knight Riders face a do-or-die situation to keep alive their fading semi-final hopes as they meet the in-form Rajasthan Royals in an Indian Premier League match here on Tuesday.The Royals, the most inexpensive side in the tournament bought by their franchisee owners for $67 millions, have emerged as the surprise package of the meet and are now sitting pretty at the top after sealing a last four slot. Having triumphed in eight of their 10 outings, the Royals have so far collected a whopping 16 points, to leave behind close challengers Punjab Kings XI (14 from 10) and Chennai (14 from 11).
