Tenace debuted against Carlton in Round 2, 2004. His first season was fairly impressive, earning an AFL Rising Star nomination in Round 6, and winning Geelong's Best First Year Player Award.
2006
In 2006, Tenace completed his third season at senior level and had a reasonable year. He played the first eight games, but managed only another six after injuring his knee and missing rounds nine to twelve. In Round 14, he had a career-high 21 disposals against Carlton.
2007
Tenace began his fourth season in the AFL impressively, averaging just over 19 possessions a game, including a career-high 28 in Geelong's round eight win over Fremantle.[1] However, he was struck down with hamstring problems in the second half of the season after playing his last senior game for the season in round 14.[1] These injuries caused Tenace to miss playing in either of Geelong's winning AFL and VFL Premiership teams.
At the conclusion of the season, after attracting interest from several AFL clubs, Tenace agreed to a new two-year deal to remain at the club until at least the end of the 2009 season.
2009
Kane Tenace had a disappointing season, which resulted in him being delisted from Geelong.[1]
