Gloucester's Andy Hazell will miss Gloucester's Zurich Wild Card final on Saturday and England's summer international schedule after medical experts advised a period of rest following a recent head injury.
The 27 year-old open-side flanker saw a neurologist this week, and after further discussions with both the Club's and England's medical teams, it was agreed that Hazell would miss the final club game of the season and England's fixtures against the Barbarians and the Churchill Cup tour.
Hazell is still suffering symptoms of concussion after two knocks to the head against London Irish at the end of March and against Saracens on 30 April.
The medical teams will monitor Hazell's situation throughout the summer and he will return to pre-season training when he is symptom-free.
Commenting ahead of Gloucester's Zurich Wild Card final, Hazell said: "It's frustrating not to be part of Gloucester's final run-in and England's summer fixtures, especially having been injury-free all season.
"But I've seen the specialists and they've advised the rest period over the summer, by which time hopefully I'll be symptom-free, which will allow me to get back and fully fit for next season. It would have been nice to finish off what has been a good year for me personally with the England tour, but it just wasn't meant to be."
Speaking to the local media this week, David Humphreys insisted that Gloucester are looking forward to kicking off the new European Rugby Challenge Cup against Brive on Thursday evening, although an unfamiliar opponent and a five day turnaround will pose a challenge.
Director of Rugby David Humphreys felt that his Gloucester side put themselves in a position to put Saracens under real pressure at Allianz Park on Saturday, praising his team's commitment and defence, while admitting that a lack of accuracy hit their chances in the second half.
Speaking to the local media at Allianz Park, Tom Savage was disappointed after the defeat at Saracens, but claimed Gloucester did plenty of good things and could've taken more than a losing bonus point.
In case you missed it, there was plenty of activity on the official Gloucester Rugby website following the 55-0 European Rugby Challenge Cup win over CA Brive, including a number of post match video interviews.
The Cherry and Whites ran in six tries in beating CA Brive 55-0 on Thursday night. An emphatic second half performance saw the hosts run in five tries to get the European campaign off to a flying start.
Gloucester took their time to go through the gears in Thursday's European Rugby Challenge Cup opener but turned on the style in the second half to emerge 55-0 winners and get their campaign off to a winning start.
