Now if its a tiger or lion against grizzly bear we have this:
According to research, the Grizzly will slaughter the Tiger or Lion.

Huge grizzly bears:
However, the 1000 lb plus bear is king here and of a much more ferocious disposition. Two large male tigers were found killed by such animals in the year 2000, which is tragic, if natures way.
Tigers will usually avoid such a powerful foe, but eventually these huge animals will run into each other. Often the bear is trying to steal the tiger’s kill. The tiger gives a better account of itself in a bear fight than the lion. The bear does not go in for strangulation or nape biting, but uses his paws to rain blows to the head and shoulders. Possibly this removes any advantage of a mane.

Grizzly bear pit fights:
The Californians of the late 19th century staged well-documented pit fights with grizzlies and spanish bulls. The grizzlies, using their paw as a club, shattered the unfortunate bull’s skull or shoulder bones so easily that the betting became poor.
Eventually, and at considerable cost, African lions were brought in to raise the stakes. The most fierce of the adult males was sent in whilst the grizzly was already waiting in the pits. The lion was known for bravely charging straight in and looked good for the money, but the grizzly killed a male lion almost as easily as he’d killed the bull.
The Californians never understood why. We now know that it was enormously strong bone density meeting a low density skull. At a range of 4 feet the blow crashed in before the lion could apply the wind pipe lock, which is lion and tiger learnt behaviour for taking down prey animals.
The ferocity of this animal easily matches that of an unsettled African lion.
