I was down that I couldn't play [against West Indies] because I had a lot of family and friends there
Ireland captain Trent Johnston is confident he will be fit to play against England in their World Cup Super 8s match on Friday.
All-rounder Johnston injured his shoulder in the win over Pakistan and sat out the defeat to West Indies.
He only started bowling again on Tuesday after having a cortisone injection in his left, non-bowling shoulder four days ago.
"I'm 100% sure I'm going to play; the physio is 70% sure," he said.
"I don't want to sit out any more games unless I definitely have to because this is going to be my last World Cup and I want to be a part of this.
"I bowled about a dozen balls today and it went OK and I'll have a bit more of a bowl tomorrow.
"I have been doing some fitness work and some therapy work on the shoulder just to strengthen it up.
"It's not going to be a problem for Friday. I'll have another fitness test on Thursday but I'm definitely looking to be part of the game."
Johnston, 32, said diving in the field remained his greatest concern as he could snap a tendon.
It was in taking a spectacular catch to dismiss Pakistan's Azhar Mahmood that Johnston damaged the shoulder, but missed out on a dream appearance against Brian Lara and co.
"I was down that I couldn't play because I had a lot of family and friends there who have now gone back and my parents were over from Australia," he said.
"I was mainly disappointed for them as they watched me twice and paid a lot of money."
