Richmond has emerged as a suitor for free agent Crow Brad Crouch, reports SEN's Sam Edmund.

Several clubs have been linked to the star midfielder, including Geelong, Essendon and Port Adelaide, with the Cats considered to have the strongest interest in him.

However, Edmund reports that the Tigers are a "sneaky chance" to land Crouch, having quietly been monitoring him for some time.

The 26-year old was involved in an alleged drug bust by police on Monday morning in an indiscretion that will reportedly cost him a significant amount of money in free agency.

It is believed that live CCTV footage from Adelaide's CBD caught Crouch and teammate Tyson Stengle in the back of a taxi with possession of a prohibited substance.

AFL Media's Damian Barrett reported on Tuesday that it will cost Crouch "a collective hundreds of thousands of dollars".

"It's caused a drama for him from a financial perspective moving forward. We know that he was going to exercise his rights as a free agent," Barrett said on Triple M.

"There's no doubt that he's knocked off a collective hundreds of thousands of dollars off his potential currency when he comes to that next stage and phase of his footy life given what he's done during the week.

"There's no doubt that clubs will now reconsider the offers that they've given him and some clubs may even reconsider continuing to pursue him in that free agency."

Richmond could likely not compete with the big-money offers from rival clubs, but can offer him an opportunity to be apart of a winning culture and compete for premierships.
