Pulis and his coaching staff had to abandon a session as the tackles flew in thick and fast at their start-of-the-art facility.
He ordered the players back into the changing room as he was afraid someone would get hurt ahead of the home Barclays Premier League match against Bolton.
Pulis said: "The lads have worked really hard. If you had seen them train Tuesday you would not have thought they had played a game (they drew 1-1 with Cardiff in the FA Cup on Saturday).
"It was one of them where we had to stop training. It was really competitive and we had to bring them in so no-one was injured. They were that fired up. I hope they are that fired up on Saturday.
"When they train, they train properly. They come in 40 minutes before we go out to do their core work and individual programmes that people have laid out for them. It gives the players a better chance to prolong their careers. When you consider the pace of the game and the tempo it is played at, they know they have to look after themselves."
