Subiaco product Jarrhan Jacky has been cleared back to his original club but is not likely to play for the Lions for at least a month as he recovers from a knee reconstruction.
The Lions paid Peel $10,000 to clear the former Adelaide midfielder, with another $10,000 due next year if he continues to play.
Jacky was coach Jarrad Schofield's runner last week but is still in the main Subiaco rehabilitation group and won't be considered for senior selection until midway through the season.
He ruptured an anterior cruciate ligament early in his second match for the Thunder last year. He played at Swan Districts for the previous two seasons.
Jacky played three matches for Adelaide after being taken at No.30 in the 2007 AFL draft.
The former Subiaco colts player spent three seasons with the Crows.
Jacky is the eighth senior player recruited by Subiaco this year after an off-season raid that netted de-listed Gold Coast midfielder Kyal Horsley, Swan Districts duo Shaun Hildebrandt and Wayde Twomey, West Perth pair Frank Stockley and Joel Latham, and Victorians Lachlan Delahunty and Matt Boland.
The Lions also poached livewire forward Shane Yarran from under Peel's nose.
The unknown 25-year-old has kicked 14 goals, including four in a best-on-ground effort in the win over Perth last week
The recruits have been instrumental in Subiaco remaining at the top of the ladder since round two.
