England opted to go into the game with just four recognised bowlers in the attack as they bid to bounce back from their Headingley defeat, which leaves them 1-0 down in the series.
The 29-year-old Harmison, who has 41 first-class wickets this season, appears to have rediscovered his pace and control but was still left out by Peter Moores, a decision that Harker disagrees with.
"I'm disappointed for Steve that he's not in the side. He has bowled extremely well for us all season and we've been delighted with his form," he said.
"We have seen enough of him this year to know that it will be difficult for England to win without him.
"I'm sure it will only be a question of time before he's back in the England side."
