Richmond is uncertain when captain Chris Newman will recover from a knee injury and be ready to resume playing.

Newman strained his posterior cruciate ligament during the first quarter of yesterday’s match against Geelong at Etihad Stadium and was ‘subbed’ off.

The 29-year-old had scans this morning, which revealed that no surgery was required.

“At this stage, it is difficult to put an exact time frame on how long Chris will be on the sidelines, but we’re hopeful he will be available for the last portion of the season,” said Richmond Football Manager Ross Monaghan.

Richmond’s other injury concern from Sunday’s loss was young defender Jake Batchelor, who suffered slight concussion.

Batchelor is expected to recover in time for the Tigers’ next match against West Coast, at Subiaco, on August 7.
