London Irish and England scrum-half Paul Hodgson has praised injury replacement Darren Allinson.
Hodgson suffered concussion against Harlequins in October, leading to Welshman Allinson getting a run in the Exiles' first team.
"Darren's playing incredibly well, he's worked hard in the year-and-a-half he's been here," Hodgson told BBC Berkshire.
"We've got competition in every position, and with Ross Samson as well scrum-half is no exception."
On the advice of the club's medical staff, Hodgson now wears a protective scrum cap during games.
But while the 29-year-old acknowledged the concussion was the worst he has suffered, he insists it has not affected his game and that he is back to his best.
Hodgson's contract with London Irish expires at the end of the season, but he said he would be delighted to stay at the Madejski Stadium.
"This is my eighth season here, it's a place which has got a really good buzz about it. We've got a lot of good young players, and Toby Booth and Mike Catt are doing an outstanding job.
"It's a place any player would want to be, so I hope to stay here as long as I can," he concluded.
