Whakaotihia te rerenga e whai ake nei: Ko Tyrell te whiringa tuarima o te Prince George Cougars i te Western Hockey League (WHL) Bantam Draft i te tau 2004. I puta ia i roto i te kēmu kotahi i taua wa i mua i te whakatū i a ia ano hei kaihautū ki nga Cougars i te 2005<unk>06. I eke ia ki te 30 ngā whāinga i tōna tau tuarua, ā, i kōwhiria ia i te rauna tuarua o te
2007 NHL Entry Draft e te Tampa Bay Lightning. I tua atu, i hanga e ia tona tīmatanga ao mo te kapa rangatahi Canadian i te 2007 Super Series, ka piro i tetahi whāinga i roto i te waru kēmu, engari kihai i taea te hanga i te kapa mo te 2008 World Junior Ice Hockey Championships.
