**The Ospreys will be bidding to turn up the heat on the Scarlets in the race for the Welsh Shield when they welcome the Dragons to Swansea on Sunday.** Last weekend's 54-36 derby triumph over the men from Llanelli pulled the Ospreys to within five points of the Shield leaders with a game in hand. Should Toby Booth's men claim a bonus-point win this weekend, then simply matching the Scarlets' performance in the final round would be enough to secure Heineken Champions Cup rugby next season. The sides would be level on points but the Ospreys have the edge when it comes to matches won. Wales international George North returns to the Ospreys starting line-up for the first time in a year, slotting in at outside centre. Academy product Will Reed will make his full debut for Dragons, who have Ollie Griffiths back after injury.
