The frontman is set to join up with the Harambee Stars squad ahead of their games against South Africa.

Blues head coach Rob Elliot said it is not yet clear if Obiero will be fit to play for his country in their AFCON qualifying double-header.

Either way, the striker will miss Carlisle’s league clash with Boston United next weekend.

Elliot is confident Obiero’s ankle injury is not serious and United will now have a watching brief to see whether he can prove his fitness on international duty.

On the 25-year-old’s absence from Saturday’s victory, Elliot said: “Micah is a great lad – he tried to train on Friday, he strapped it up but he just was too sore.

“It's not a bad one with Micah, but it's swollen. Until the swelling goes down, it won't settle.

“He'll go away with Kenya on Monday because he's got to report for duty.

“We'll see whether he's available for them and if not, whether he comes back.

“I'd imagine either way, he won't be available next weekend because of the situation.

“But fingers crossed, we don't think it's too serious. [On Saturday] it wasn't worth the risk and he wasn't able to play anyway.”

Benni McCarthy's Kenya are due to face South Africa in an away clash on Friday at Orlando Stadium, before hosting Bafana Bafana in the return game at Nyayo National Stadium in Nairobi on Tuesday week.

United midfielder Teddy Jenks is continuing to be monitored, meanwhile, after missing the cup clash with a knee injury.

Elliot expects the former Worthing man back soon but stopped short of confirming that  Jenks would be fit to face Boston.

“Next Saturday…maybe, but he took a whack and it's sore and it's stiff,” said the Blues boss.

“So we have to be careful with that one. We want to make sure it doesn't turn into anything [more serious].

“Sometimes you can rock the joint and it does take a couple of weeks to settle down.

“But we don't think there's anything structurally too wrong.

“We'll see how he is next week. If it doesn't settle down, we'll maybe go and speak to someone. But I'm quite confident it's nothing too major.”
