Gloucester coach Nigel Davies threatens to make changes after three of his players are sin-binned In his absence, tries from Nick Easter and Danny Care, complimented by two Evans conversions, added 14 points to Quins" total. Gloucester's indiscipline rumbled on in the second half as captain Tom Savage and Martyn Thomas were also handed yellow cards. Luke Wallace extinguished any Gloucester hopes with a try shortly after the restart, although Twelvetrees and speedy Jonny May touched down as Quins" George Robson was also sent to the bin. Conor O'Shea, the Harlequins director of rugby, said: "What a great way to mark 50 years of rugby at Twickenham Stoop. People say we are struggling, but we are near the top of the table. Although we lost our momentum, this was our third straight Premiership win. That gives us confidence to take into the game against Newcastle on Sunday. There were lengthy delays as the Referee Academy's first graduate Matthew Carley checked several replays. But O'Shea backed the 28-year-old, insisting: "The official can take his time: it's vitally important to get the right decision with points on the line. This is a results business and points mean a lot come the end of the season.
