Prakash Amritraj's brilliant run at the euro 85,000 ATP Challenger event in Rhodes, Greece, ended on a disappointing note, the Indian conceding his semi-final match due to a leg injury.
Up against seventh seeded German Benjamin Becker, Prakash was trailing 1-6, 2-4 when he opted out of the contest.
He had stunned world number 59 and top seed Dudi Sela in a gruelling quarter-final to reach the last-four stage.
Prakash got 35 ATP ranking points and euro 4,260 as prize-money for his effort.
Indian Davis Cuppers Rohan Bopanna and Somdev Devvarman, had already exited from the tournament.
