Norwich City midfielder Alex Tettey has said he would struggle to play in three games in a week.
The 28-year-old has suffered from a recurring knee injury during his three seasons at Carrow Road.
And he has started just two of the five games overseen by new manager Alex Neil, who was appointed in January.
"I can't play three games in a week. I could do it - but I don't think my knee would like that," he told BBC Radio Norfolk.
"Some of the boys want to play all the time. Bradley Johnson can do it all the time, so good luck to him.
"But others will want to manage the situation."
Tettey could be in line to feature at Charlton on Tuesday night, as the play-off-chasing Canaries look for a fourth win from six games.
But the Norway international suggested there were more than just tactical reasons for his omission from the side in Saturday's 4-0 win over Blackpool.
"The other reasons I cannot say. That's just between the manager and me," he said.
"The gaffer spoke to me and I accepted it and there is a game on Tuesday, so we will see."
