Adelaide's Luke Brown in clear for Hawks clash Emerging Adelaide Crows defender Luke Brown has passed a concussion test and is fit to play this weekend. YOUNG Crows defender Luke Brown passed a concussion test at West Lakes today to be clear for action against AFL premiership favourite Hawthorn at AAMI Stadium on Saturday. Brown's confirmation allows Adelaide to stay with the 22 players named at selection on Thursday night and keeps Richard Tambling on the emergency list. The most significant news from selection is the return of key forward-ruckman Shaun McKernan to the line-up for the first time this season as Adelaide copes with the loss of key forward Taylor Walker for the rest of the season with a knee injury. Adelaide assistant coach Scott Camporeale noted his midfield unit would be seeking to supply a new-look attack. McKernan is listed as partnering Josh Jenkins in the Crows forward line, replacing the Walker-Tippett tandem that pushed the Crows to within five points of the Hawks in last year's preliminary final. "Josh Jenkins has been there for the whole year, Tom Lynch has come in for the past fortnight, so we need to generate more goals midfield-wise and hit the scoreboard from there to pick up the slack," Camporeale said. Shaun has been in really good in the SANFL. He kicked five (with Glenelg at the weekend) so he deserves an opportunity. He is probably like for like with 'Tex' (Walker). That's probably really the only change. Off-field, the change in the Adelaide Football Club's front office at West Lakes has begun with Craig Burton, the general manager of marketing and communications, no longer in his position. It is considered the start of a reshuffle of the Adelaide administration.
