RICHMOND tall Ben Griffiths' hopes of making an AFL comeback have hit a roadblock after he suffered a right shoulder injury in the VFL against Collingwood on Sunday.

It was the 25-year-old's second game back following a two-and-a-half-month layoff after repeated concussions.

Griffiths contested a centre bounce early in the second term at the Punt Road Oval and followed up his efforts by attempting to tackle a Magpies opponent on the wing, only to injure his shoulder in the heavy contact.

The 200cm forward immediately went to ground clutching his arm and was assisted off the ground by trainers.

He did not return for the second half.

Griffiths made his comeback last weekend via the VFL, kicking two goals before being rested in the second half against Werribee.

He suffered his latest concussion in round two this season after landing heavily in a marking contest in the third quarter against Collingwood.

In his absence, the Tigers turned to inexperienced rookie Ivan Soldo and tall forward Todd Elton at various stages as support for Jack Riewoldt. 

The club has also played a small forward line with some success while anticipating Griffiths' return later in the season.
