RICHMOND midfielder Nathan Drummond visited renowned knee rehabilitation specialist Bill Knowles in America as part of his recovery from the ACL injury he suffered on debut in round four last season.
The 20-year-old was accompanied on the trip by Richmond's rehabilitation and conditioning coach Luke Meehan as he makes solid progress towards a return to full training.
Drummond ran laps at Punt Road on Friday morning and the club's physical performance manager Peter Burge told the club's website early in the week they were rapt with his progress.
"It's going fantastically well," Burge said.
"He had a very, very specifically targeted program over the Christmas break and this week we are starting to see him progress to another level with, his change of direction, his confidence and his ability to jump and land."
Drummond missed 2015 after suffering the knee injury in the first half of his first game in round four against Melbourne.
Several young AFL players have visited Knowles after suffering knee injuries including Melbourne's Christian Petracca and Greater Western Sydney's Jonathon Patton.
The Tigers felt the benefits will help Drummond and also their ability to manage other injuries in the future.
Richmond's Alex Rance is also back into full training after an extended off-season break in America and the Tigers are pleased with the progress of the players traded and drafted into the club with Daniel Rioli's skills standing out.
Former Carlton speedster Chris Yarran, who joined the Tigers in the trade period, is progressing well but he did not train on Friday due to illness.
