Schindler, who was one of a host of Terriers to excel in an outstanding team performance over the Londoners, went down after a saving tackle to deny Bright Osayi-Samuel and was attended to by the club’s medical staff for a number of minutes.
After getting to his feet, the German hobbled off the pitch with the help of Town staff members.
It was the one downside to an impressive afternoon for Town, who turned in arguably their best performance of the Corberan era and produced an excellent reaction following their 3-0 midweek defeat at Cardiff City.
Josh Koroma put Town ahead with a brilliant third-minute curler and Harry Toffolo’s first home goal for Huddersfield doubled the hosts’ advantage in the 39th minute.
On the situation with Schindler, Corberan - who is without another experienced defender in Richard Stearman for a significant length of time - said: “He's not in good condition and we need to give him a scan and evaluate with the medical staff exactly what the injury is but it looks like his knee. It can be a complicated injury but we will need to see.
“Until that moment, he was having a fantastic performance - one of his best performances for me.”
Corberan heaped praise on his side after producing a fine display of incisive football against Rangers, who could not have complained if they were on the receiving end of a much heavier defeat.
By contrast, Corberan’s counterpart Mark Warburton was left to reflect on a ‘very bad day at the office’ and admitted that his R’s side were ‘second best all over the park.’
Corberan commented: “It was a quality performance with a lot of good individual performances. From the first minute, we deserved the three points.
“It was important for me for us to react to the defeat with a high level of character and confidence.
“It's always important for your forwards to do their jobs.
“We attacked in the opposite way to how we did against Cardiff. All of the front line did their job did really well and helped to create chances.”
