Glasgow: Jamaican Yohan Blake has suffered another setback on his return to action following injury when he pulled up with an apparent injury in the 100 metres at the Glasgow Grand Prix here.
The Olympic silver medallist on Friday pulled up after 70 metres holding his left leg, and had to be taken from the track by wheelchair at Hampden Park, reports CMC.
Blake only recently returned to competition, after recovering from a hamstring injury that wrecked his season last year. He opted out of the National Championships last month and subsequently said he would also miss this month's Commonwealth Games carded for Glasgow.
His misfortune overshadowed a fine run from his Jamaican compatriot Nickel Ashmeade who clocked a season-best 9.97 to win the 100 metres, in a tight finish of the top three.
American Michael Rodgers was second in the same time while Nesta Carter of Jamaica was third in a season-best 9.98 seconds.
Veteran St Kitts and Nevis sprinter Kim Collins clocked a season-best 10.07 to finish fifth, with Trinidadian Richard Thompson getting in sixth in 10.09.
In the men's 200 metres, Olympic bronze medallist Warren Weir of Jamaica trailed in second in 20.30 seconds as Panamanian Edward Alonso reached the line first in 20.25.
Meanwhile, Jamaican Novlene Williams-Mills suffered a second straight defeat in the women's 400 metres, losing out to rising American star Francena McCorory.
Williams-Mills was third in 50.60 as McCorory took victory in 49.93 seconds, with Olympic champion American Sanya Richards-Ross second in 50.39.
There was also disappointment for Hansle Parchment who only last weekend broke the Jamaica national record in the men's sprint hurdles, as he could only manage fifth spot in 13.31 seconds.
William Sharman of Great Britain clocked a personal best 13.21 seconds to win the event, with former World champion Shane Brathwaite of Barbados trailing in last in 13.62.
