The AFL has confirmed St Kilda has made an official offer to restricted free agent Brad Crouch on Sunday.

The League have received the paperwork from the Saints and are currently processing the details.

Meantime, Adelaide is now in a three-day period where the Club can decide whether or not to match the offer.

“The club is aware of the free agency offer lodged for Brad Crouch this afternoon," Crows Head of Football Adam Kelly said.

"We will await the determination of free agency compensation by the AFL and then review our options before making a decision in the club’s best interests.”

The three-day period concludes at 5pm AEDT on Wednesday November 4.
