Richmond defender Graham Polak is now able to remember the Tigers' loss to Carlton on the day he received brain injuries when hit by a tram.

Polak continues to improve since he suffered bruising to the brain when struck by the tram and put in an induced coma on June 28.

"In the past few days, Graham's memory recall has improved," Richmond Football Club said in a statement.

"He has started to remember some aspects of the game against Carlton which was the day of the accident."

Polak, 24, remains in Epworth Rehabilitation Centre and the club said his recovery "will take quite some time".

"I am extremely pleased to see the progress Graham has made from when I visited him mid last week," coach Terry Wallace said.

Wallace and director of football Greg Miller visited Polak on Monday and delivered some of the 1,500 messages of support the club has received for him.

Club doctor Greg Hickey said Polak has been undertaking regular physiotherapy and exercise and is sleeping well at night.

"He still has a long way to go but he is getting back to being the old Graham we all know," Dr Hickey said.

Polak awoke from the induced coma last Monday, two days after being hit by the tram as he crossed a street in inner Melbourne around 11.30pm on June 28, hours after Richmond lost to Carlton.

The club said it was unclear how long Polak would remain at the Epworth Rehabilitation Centre.
