Newcastle Falcons advanced to the quarter-finals of the European Rugby Challenge Cup on the back of 21 unanswered points - either side of the interval - in a 28-24 victory over Ospreys. Ospreys’ Justin Tipuric and Adam Beard were sent to the sin-bin late in the first half, Newcastle taking full advantage with tries from Trevor Davison, Sean Robinson and a penalty try to overturn an early 14-0 deficit. Kieran Williams and Dan Evans had given the Welsh region the early lead with two tries in three minutes before Newcastle's concerted comeback. Replacement Philip van der Welt extended the visitors lead to 28-17 mid-way through the second half before Tom Botha ensured a tense final 10 minutes with a try for the hosts. https://twitter.com/ERChallengeCup/status/1378376497887596548 Ospreys opened the scoring in the ninth minute as the Welsh region swiftly moved the ball through hands to the left flank – centre Williams the beneficiary of the flowing move as he touched down after an exquisite Luke Price offload. The Welsh side doubled their lead four minutes later as Evans finished off a quick-moving counter attack down the Newcastle right. 30 minutes of Ospreys dominance was squandered in a 10-minute spell at the end of the first period. Tipuric was sent to the sin-bin before Davison touched down to half the deficit to 14-7. A penalty try for the visitors, moments before the half-time whistle, levelled the tie – Beard the second Ospreys player to be sent to the sin-bin for a foul as Newcastle looked destined to score from a rolling maul in the corner. The visitors took full advantage of the two-man advantage in the opening salvos of the second half, Robinson the beneficiary of the extra space to give Newcastle their first lead of the afternoon. The teams exchanged tries as van der Welt and Botha crossed the whitewash before Newcastle saw out the game with five minutes of sustained possession, killing any hopes the hosts had of reaching the last eight of the competition. The Gallagher Premiership side now await the winner of the tie between Leicester Tigers and Connacht Rugby.
