Durham all-rounder Paul Collingwood has declared his fitness following a return to action for the county in the Twenty20 competition.
The 35-year-old made his first appearance of the season in the defeat by Warwickshire, following an operation on a knee problem in April.
"I still feel young and fit," Collingwood told BBC Look North.
"The body is doing well and after eight weeks off I'm mentally refreshed and the enthusiasm is there."
Collingwood made an inauspicious start against the Bears in his one T20 outing this term, while Sunday's trip to Worcestershire was washed out by rain.
With the bat a combination of Darren Maddy and Will Porterfield saw him dismissed for just seven runs, while two overs of bowling conceded 15 runs without a wicket.
Collingwood retired from Test cricket with in January, a decision which was followed by his replacement as England Twenty20 captain by Stuart Broad in a three-pronged captaincy system.
However the Shotley Bridge professional remains philosophical about the decision, with his focus switching to domestic matters with the county he first represented at first-class level in 1996.
"You can't ask them to go back to a re-vote, but I'm still keen to be involved and I fully respect the management and theyt're moving England forward all the time," Collingwood continued.
"If I can put some big performances in for Durham and win some games, that's my priority at the moment, and hopefully I'll get back into the England set-up.
"Whatever happens with England from now on I've had a good career, but I still want to be involved."
As captain the all-rounder led England to the ICC World Twenty20 last year as well as a record eight straight short-form wins.
