RICHMOND is unable to say when Dylan Grimes will return to the field after the injury-riddled defender underwent hamstring surgery on Tuesday.
Grimes, 21, hurt his left hamstring at training on Friday. Scans showed he had a ''nick'' in the tendon.
It was the third time this season that same hamstring had been an issue.
Tigers' elite performance manager Peter Burge said he was unsure when Grimes would resume.
''Given Dylan's history with hamstring injuries, we believe surgery was the best option,'' he said.
''Despite the setback, Dylan is keen to start his rehabilitation and is hopeful of being ready for the start of the 2013 season.''
Grimes had been training well until the latest setback.
He is considered a key component of the Tigers' back line but has been restricted to 17 matches in three seasons because of repeated hamstring troubles.
Earlier this year, he was sent to Germany for treatment with soft-tissue specialist Dr Hans-Wilhelm Muller-Wohlfahrt.
If Grimes' hamstring woes continue, the Tigers, who have struggled to contain are likely to even be more thankful they recently recruited former Port Adelaide key defender Troy Chaplin.
