One of Old Glory's three Canadian players, Doug Fraser, has been named to the extended roster for Canada's July and fall tests. Like his American teammates on the extended US Eagles roster, he will have to wait for the roughly 30-strong travelling roster to be announced before he will know whether he will be heading to England in July. That announcement will likely happen towards the end of June. Fraser has four caps already with Canada.
It's unclear how much time Fraser will miss if he does join the travelling team. While the US team has stated that players will only be unavailable for two weeks, Canada hasn't made a clear statement. Regardless, we'll likely see more of Sam Cusano and D'Montae Noble during the July test window.
