RICHMOND is hoping to offer talented WA teenager Sydney Stack an AFL lifeline, with the Tigers inviting him to train at Punt Road.

The Tigers submitted a request to the AFL over the weekend and is waiting for League approval.

If given the green light, Stack will arrive at Tigerland on December 1, and can train with Richmond during the pre-season supplemental selection period until March 15.

He could then join Richmond's list under the new rookie rules.

The speedy midfielder was regarded as one of the most talented of WA's draft hopefuls but was overlooked in last week's NAB AFL Draft and Rookie Draft.

Stack missed the first round of the NAB AFL Under-18 Championships following failure to meet training standards, but quickly made up for lost time with an impressive carnival for WA.

His good form earned him selection in the Under-18 All Australian team, as well as a debut for Perth's Colts side in the WAFL in round 19.
