Richmond will be without experienced duo Daniel Jackson and Ricky Petterd for this Friday night’s match against West Coast, due to injuries.

Jackson has been ruled out for at least a fortnight as he battles a glute injury, while Petterd (finger) is likely to be available for the Tigers’ Round 19 game against Greater Western Sydney.

Jackson has missed a total of six games this year – the first two matches of the season as he worked his way back from an interrupted pre-season, and a four-game stretch from Round 12-15 due to a hip injury.

In other injury news ahead of the clash against the Eagles, Reece Conca will bid to prove his fitness on the training track this week, after suffering concussion against Port Adelaide in Round 17.

Youngster Ben Lennon (concussion) and midfielder Shaun Grigg (hamstring) are also a chance to be available this weekend.
