The winger is now set for scans in the coming days to assess the extent of what appeared a left hamstring issue.
Ahmed stayed on the pitch for the closing moments of the opening period, but was clearly struggling and did not reappear at the MKM stadium.
The 25-year-old has established himself in the Canadian set-up over the past 18 months, and made no secret of his excitement at potentially featuring in a home World Cup since his arrival in England.
Amankwah Forson also picked up a first half knock in what Clement felt was a harsh outcome on Humberside.
“Let’s hope with Ali, it’s not too bad,” said the City boss, with the Belgian allaying any World Cup fears in the build up around the absence of Scottish international Kenny McLean. “With Forson, of course, also, but Ali has a World Cup coming up, so let’s hope it’s not too bad. We’re going to take a scan and assess in the next few days.
“It was not a game that we deserved to lose. We spoke about that this week, about going into a game where you don’t have anything to win any more, but my players showed the right mentality, and they went until the last seconds trying to get the result.
“I think also for everybody who’s maybe not a Hull fan who saw the game will say that we deserved more also out of this game so, but it didn’t happen. We concede two goals that we can stop.
“We need to get a penalty also on Paris (Maghoma) at the end. But those things are done, and it’s not important to talk about any more, because the result is there.
“That’s also the Championship that referees decides without any technology, and we need to focus on ourselves. What we missed to have a really good game is to be more ruthless in the final third. That’s the part that we missed.
“All credit to Hull, and I’m really happy for them that they can go to the play-offs, because I have two ex-players there also, but we did our job to get our result. We gave everything as a team for that, and I think we deserve more.”
