**The international window stretches squad depth across the domestic game, so Ulster will no doubt be feeling relieved today after two of their key players returned from injury.** \n\n[Fly-half Billy Burns and centre Luke Marshall both returned to training](https://www.belfasttelegraph.co.uk/sport/rugby/ulster-rugby/ulster-pair-return-to-training-in-injury-boost-ahead-of-prolonged-international-window-39648018.html) on Tuesday and look set to feature against Dragons at the Kingspan on Sunday. \n\nMarshall could play for the first time since lockdown due to a hip injury while Burns has missed the start of the season. \n\nUlster have made an unbeaten start to the new campaign but will be forced into several changes with Jacob Stockdale, Stuart McCloskey and Rob Herring away on Ireland duty and Iain Henderson injured. \n\n"In terms of injuries, we won't have many coming back but I think Billy Burns is close so it's good to see him back in training and Luke Marshall as well," said the side's attack coach Dwayne Peel. \n\n"Those are two big positives to see those guys back running around." \n\nThere will be plenty of Guinness PRO14 players strutting their stuff for the Lions next summer and organisers have today announced another fixture to the tour. \n\n[The Lions will host Japan at BT Murrayfield on June 26, just before they fly out for the tour in South Africa](https://www.lionsrugby.com/2020/10/21/british-irish-lions-to-play-japan-in-edinburgh/).
