West Ham United have been wheeling Robbie Keane into an ice chamber in a bid to speed up his recovery from a calf injury.
The Republic of Ireland striker was West Ham's key January signing in a bid to avoid the drop but he damaged a calf in training and is facing weeks on the sideline.
The Hammers are looking to trim the recovery period by putting him in a chamber that plunges to sub-zero temperatures.
"Robbie and I had to sit in the chamber at minus 140 degrees for five minutes at a time," said Hammers midfielder Jack Collinson who is battling to overcome a knee injury.
It proved to be a strange experience for Keane and Collinson who were joined in the chamber by boxing legend Frank Bruno.
"We had to share the chamber with boxer Frank Bruno," Collinson said. "It was great to meet him but he made us look really weak. He was in there doing all kinds of exercises and Robbie and I just sat there trying to keep warm."
