However, the 41-year old promised fans that they will see “a real fighting performance” on Wednesday when his side travels to Birmingham.
A late Karlan Grant penalty put the visitors on the board but goals either side of half-time from Lewis Grabban and an 85th-minute strike by Ryan Yates had already condemned Huddersfield to their third consecutive Championship defeat.
Juninho Bacuna was sent off in the 89th minute which only added to Huddersfield woes on what was a miserable day at the City Gr0und.
With seven fixtures remaining, Huddersfield sit 22nd in the table, level on points with Hull City but in the relegation zone on goal-difference.
Speaking to BBC Radio Leeds, Cowley said:
“We are on the floor at the moment, but we haven’t been counted out,
“We are getting up and we will go again – we will get to Birmingham (on Wednesday) and you will see a real fighting performance. Then we will dust ourselves down and then you will see another fighting performance against Preston (on Saturday).”
“Maybe we have one or two that feel sorry for themselves, I think it’s fair. But there is no time to. No-one else is going to feel sorry for us.
“We have to suck up the disappointment. It is not a good time to lose three games on the trot.”
