Leicester manager Nigel Pearson acknowledged that the Foxes had been well beaten in their final home match of the season against West Ham.
The third-placed Hammers kept their automatic promotion hopes alive with comeback 2-1 away win at the King Power Stadium.
Jermaine Beckford headed Leicester in front against the run of play, but the East Londoners responded quickly through Winston Reid before Jack Collison smashed home the winning goal in the second half.
Pearson felt injuries hampered his side's chances during the game as captain Richie Wellens limped off after 22 minutes and fellow midfielder Andy King failed to re-emerge for the second half.
"It is a disappointing way to round off the home campaign," he said.
"Their clinical finishing was the difference but in the end they had too much for us and I have no complaints.
"Richie Wellens will have a scan on Tuesday. It doesn't look promising at the moment. And likewise with Andy King, who has a foot injury that is maybe
similar to his original injury but hopefully isn't as bad.
"They are things we could do without at this stage of the season, certainly with our numbers being short in midfield.
"We didn't have the creativity in the middle of the park that we would have liked and I think that - along with the injuries - didn't help us tonight.
"It also affected what we could do to try to get back into the game.
"It was good to get Martyn Waghorn back out on the pitch for the first time since October. I would have liked to get Darius Vassell on as well but the injuries in the first half again limited what we could do."
