RICHMOND could send teenaged defender Dylan Grimes to Germany to seek treatment for his troubled hamstrings.

The Tigers, still in the hunt to play a role in September, have revealed their star defender could be flown overseas this month for an appointment with Dr Hans-Wilhelm Muller-Wohlfarth, a world leader in the treatment of soft-tissue injuries who famously treated former Cat Max Rooke on the eve of the 2007 finals series.

Having revealed that Tyrone Vickery's accursed 2012 season was finished and the ruckman-forward would next week undergo a shoulder reconstruction, Richmond appears to have been optimistic in its claim Grimes could be available within four weeks.

The revelation came after the Tigers' horror trip to Adelaide at the weekend that dealt a blow to their finals hopes when they failed to defend a 33-point quarter-time lead. The Tigers also lost inspirational forward Jake King for at least a month and, last night, failed in their appeal against Daniel Jackson's latest suspension.

But the loss of Grimes looms as the biggest disappointment. The talented young backman suffered a season-ending hamstring injury last year and then injured his other hamstring in the Dreamtime game against Essendon in May.

Having just returned from injury, Grimes sustained a hamstring tendon injury in his left leg during the Adelaide game and appears no realistic chance to return to the side until the Tigers' second-last home-and-away game against Essendon in round 22.

In 2007, Geelong spent a reported $20,000 on sending Rooke to be treated by Muller-Wohlfarth in Germany for a hamstring injury before the finals. On returning, Rooke played in Geelong's premiership and was part of another in 2009.

Richmond sent Mark Coughlan, who also battled hamstring injuries, to Muller-Wohlfarth in 2008. Coughlan was injected 102 times with Actovegin during his treatment.

Vickery has missed the past two games with knee soreness but has been managing the shoulder problem, sustained in a pre-season game at Geelong, along the way. Injuries have dogged him this season after a highly encouraging top-five finish in the Jack Dyer Medal last year.

''We have tried to manage Tyrone through this season with his shoulder but, ultimately, it was impacting his performance and the best course of action is to get it fixed now, so he is able to complete a full 2013 pre-season,'' said Richmond's general manager of football, Craig Cameron, who confirmed the club was investigating sending Grimes to Germany.

Muller-Wohlfarth's use of Actovegin - a highly filtered extract from calf blood that improves the circulation of oxygen in humans and thereby aids recovery - is controversial. In July last year, the sale, importation and use of Actovegin was banned in the US. It is not prohibited under the World Anti-Doping Agency list, but when updates were made last September, WADA said it was ''aware of its [Actovegin's] use in some sports, possibly in conjunction with other substances that may be prohibited''.
