Richard Hill brought an end to his career after Saracens' 25-20 victory over Bristol in Milton Keynes on Saturday.
The former England flanker, whose side had to wait until the last minute of the match before the left wing Kameli Ratuvou scored the try which secured their win, said: "It's been a very special 15 years but it isn't about me, it's about the team."
The 34-year-old paid tribute to the medical personnel who helped him to return from the injury which kept him out of the game for 18 months, left him with a permanent limp and ended his hopes of defending the Webb Ellis Cup last year.
"There are many coaches throughout my career I would like to thank and I've also got a big medical list to go through," Hill said. "I've had a lot of highs away from Saracens, in terms of playing for England and the Lions, but then there have been the lows of injury in recent years. But there are no regrets. There have been setbacks but they have probably made me more determined to rise even higher."
Worcester's director of rugby, Mike Ruddock, praised his side but had sympathy for Newcastle after the Warriors' 51-10 win at Sixways.
Worcester go to Kingsholm in a fortnight to face Bath in the European Challenge Cup final.
Ruddock said: "It was great for us because things we talked about at the start of the season came right, but what a tough week for Newcastle after they had to play three games. We won the second half 31-0, which shows they were tired. We've got to temper our thoughts and reflect that Newcastle really did tie up a bit in the second half."
The Worcester-bound Australia full-back Chris Latham has played his last match for Queensland. Latham injured his shoulder in the Reds' Super 14 defeat by the Crusaders on Saturday.
Scans will deter-mine the extent of the damage but the Reds' head coach, Phil Mooney, said the injury was serious enough to bring an end to Latham's state career, leaving him on 99 appearances.Reuse content
