HAFTHOR BJORNSSON backed Anthony Joshua, claiming that he is too big for Oleksandr Uzyk - despite the challenger trying to bulk up.
Joshua defends his unified Heavyweight title in a mandatory title defense at Tottenham's Stadium this Saturday.

This will be Usyk's third fight after he moved up from the cruiserweight division. His last fight was against Derek Chisora (37), in October.
He was just 15st 7lbs and gave away nearly three stone before he won on points.
Usyk, 34 years old, has gained 16st 5lb to combat AJ's imposing frame.
Bjornsson, Game of Thrones' star and boxer who lost nine stone while training for the Olympics, is concerned about how the Ukrainian will fare after his body transformation.
SunSport quoted him as saying: "Absolutely. I will be watching 100 percent. Joshua is a little too big for Usyk, I believe.
"Usyk is an excellent boxer, but there's a height and weight difference. I believe Usyk is starting to gain weight.
BETTING SPECIAL - GET JOSHUA TO WIN IN ROUNDS 1-6 AT 60/1 OR ANYTIME AT 25/1"I don't know how it will affect his performance. He won't be used being that heavy. We don't know what he will do.
Joshua is my favorite, regardless of whether it will make him stiffer or not. He feels more at home in this weight category.
Bjornsson (known as Thor) is a Reign Total Body Fuel ambassador. He trained for over a year as a boxer.
It also includes a signed and sealed super-heavyweight fight with Eddie Hall.
Thor had three tune up exhibition bouts to prepare. The last one was against Devon Larratt (46), an arm wrestling champion.
Hall, 33, was supposed to be in the opposite corner. However, he suffered a bicep injury while training. The grudge match was postponed until March.
Thor, 32, is now back in Iceland after his trip to the Middle East. He plans to relax and watch Joshua, 31, defend their belts against the 18-0 unbeaten Usyk.
He stated, "I cannot wait to see the fight, I believe this fight will be fantastic.
"It could go either direction, but if it had to be decided, Joshua would win."
