Nothing malicious in challenge but Hyam gutted to see 'fellow pro stretchered off'
Luke was shown a yellow card by referee Philip Gibbs for the challenge, though Town boss Mick McCarthy felt that was unwarranted as he got the ball.
The midfielder was booked again and dismissed just before the break after reacting to a foul by Ryan Woods.
Cleary upset, Luke told the Club website: “There was nothing malicious in the tackle and I hope Alan recovers quickly.
“I’ve been out injured for a year myself and the last thing I want to see is a fellow pro getting injured like that. I would never wish that on anyone.
“I feel distraught over it. It was distressing to see and definitely affected me. My head had gone.
“I know the Brentford lads were getting into me but I should never have reacted the way I did to get sent-off, which was obviously disappointing on my part.
“My thoughts are with Alan though. I’d like to contact him in a day or so and just give him my best and say how sorry I am that he has got injured like that. I just hope he’s back playing as soon as possible.”
