But we heard reports the former Arsenal defender didn't KNOW Taylor was injured.
The incident happened at Newcastle's training ground last week and it left the full-back on crutches.
According to Talksport, when Taylor turned up at St James'Park to watch his side draw 0-0 with his ankle in a cast, 36-year-old Campbell thought it was a joke!
Talksport's source close to the player said: "Sol didn't apologise for the tackle at the training ground, and then thought Ryan was winding him up when he appeared at the game on crutches.
"Ryan was understandably surprised as he was clattered into by Sol, and this tackle has probably ended his season."
But Ryan Taylor insists there is no question to answer, it was an accident: “These things happen on the training ground, but it's not great for me. I face a long hard winter now."
