Noah by Ben Ryder.
Can't say I've read this one, but it's got a good review at Dreamspinner.
Description:
Callum Walker is feeling listless in his life in London. When his job takes him to Canada to install communications software for a new sports arena, he’s glad for a change of scenery.
During his stay, he befriends Noah Lukas, the strikingly handsome star player of the Toronto Bobcats professional hockey team. Callum knows nothing will ever come of it, but he can’t stop his attraction. As their bond grows, Callum learns more about – and falls more for—Noah through his sensitive and humble interactions with fans, his gentlemanly reaction to flirtations from arena staff, and his frank apprehension over his impending retirement. Their friendship evolves from workout partners to confidants, and then to even more. But Callum’s time in Canada is limited, and circumstances may divide him from a love he wasn’t looking for.
