Sussex are keeping hold of David Wiese as their T20-only overseas player – for the time being.

They have asked the South African all-rounder to stay until they are convinced pace bowler Mustafizur Rahman is fit and ready for action.

Wiese initially signed only for last week’s two home matches but has remained at Hove.

Rahman, who has a minor hamstring injury, headed home to Bangladesh after playing in the IPL.

There are fears among his national set-up that he could be suffering from fatigue.

Sussex skipper Luke Wright told The Argus: “We are lucky. We are going to be able to keep hold of David until he goes to the Caribbean Premier League.

“We are just waiting on word to find out how bad Mustafizur’s hamstring is. I don’t think it is that bad.

“David can definitely play. He will definitely be here until Friday and then we will see how it goes after that.”

Sharks host Kent at Hove in the NatWest T20 Blast on Friday.

Before that they kick off their London Victoria One-Day Cup schedule at home to Essex today and away to Glamorgan on Wednesday (both 2pm).

Wright has been impressed by Wiese’s attitude bowling from the Sea End in T20 outings against Somerset, when he took four wickets, and Surrey, when he was expensive.

And he hinted that he expected to see more of him in a Sharks shirt.

Wright said: “I feel for him. He hasn’t really played that much in the IPL and then he has come here and had to bowl the really tough end up the hill.

“I’m sure he will get a bit more of a crack as we go.

“It’s tough cricket, isn’t it? It’s hard.

“But he’s great. He has not once moaned about bowling at that end.

“What I love about him is he has gone away and said ‘Sorry skipper, I haven’t bowled well enough, I’ll find a way to get better up the hill’ and that shows what a quality player he is.

“He is going to be good for us.”

Sussex have made off-field arrangement to make Rahman feel as at home as possible when he arrives in Sussex.

Bangladesh physio Baizidul Islam believes the player could suffer burnout due to his heavy schedule.

But national team coach Chandika Hathurusingha believes playing for Sussex will greatly benefit the left-armer and, by extension, the Bangladesh team.

Hathurusingha said: “If you want to improve the performance, you have to play in those conditions.”
