Fremantle small forward Michael Walters a future midfield star Fremantle forward Michael Walters has kicked six goals in the opening two rounds. Picture: Michael Klein Source: PerthNow HE is fast establishing himself as one of the AFL's best small forwards, but it seems Michael Walters' destiny lies in the midfield. Walters has booted 19 goals in seven games this season, including a combined eight goals in recent wins against Gold Coast and Collingwood. The 22-year-old has become a nightmare for opposition defenders to contain, but showed he can be just as dangerous in the midfield with several promising stints through the middle in Saturday's 27-point win over the Magpies. Walters finished the match with 19 possessions to go with four goals, and Lyon said the 177cm speedster was on track to become a permanent midfield fixture in the future. "We see his ultimate destination through the midfield," Lyon said. Unless you're the Judds and the Pendleburys, most players do an apprenticeship in the forward line. I remember Jason Akermanis, Luke Power and those guys, they played the small forward role and then moved into the midfield. The long-term aim is Michael to go into the midfield where we know he's got the run and smarts and courage to thrive. But that's a long way off yet. Walters was banished to the WAFL early last year for failing to meet the club's fitness targets. The time away from the club worked a treat, with Walters now hungrier than ever to make the most of his AFL career. Fremantle boasts an impressive 5-2 record despite a horror injury run, which claimed another victim on Saturday when ruckman Jon Griffin suffered a season-ending knee injury. Griffin joins skipper Matthew Pavlich (plantaris), ruckman Aaron Sandilands (hamstring) and Kepler Bradley (knee) on the sidelines, but Stephen Hill is set to return from a quad injury in Saturday night's clash with Sydney at the SCG. Nat Fyfe will also bolster the midfield after serving his two-match suspension, while ruckman Zac Clarke is set to resume in the WAFL after finally overcoming a calf injury. Third-gamer Jack Hannath is likely to lead the ruck in Griffin's absence, with the likes of Zac Dawson, Alex Silvagni and Michael Johnson on hand to lend support. Meanwhile, midfielder Tendai Mzungu has re-signed with the Dockers for a further two years, tying him to the club until the end of 2015. Mzungu, 27, has played 45 games since making his debut in 2011 as a mature-age recruit.
