Steelers head coach Mike Tomlin said he has reached out to Cameron Sutton

Now, five-plus days since the warrant for his arrest was issued in Florida on an allegation of domestic battery by strangulation, there is no word regarding the whereabouts of Cameron Sutton. The Detroit Lions released him the day after the arrest warrant was made public.

Prior to signing with the Lions as a free agent last offseason, Sutton spent his first six NFL seasons with the Pittsburgh Steelers after being a third-round pick by them in 2017. As he developed into a starter for them, he of course had Mike Tomlin as his head coach for the entire six years.

Say whatever you might want to about Tomlin, but he is a player's coach and it's fair to assume he maintains contact with some even after they leave the Steelers.

Mike Tomlin says he has reached out to Cameron Sutton, stops short of saying anything else

Apart from any football implications for the Lions, and concerns for the other people in the situation, Sutton's unknown whereabouts (at least publicly) and his well-being is a concern. That the authorities don't known where he is weird, if nothing else, as they had apparently exhausted all leads they had for two weeks before issuing the arrest warrant.

At the league meetings on Monday morning, Tomlin was asked if he reaches out to players when they're in trouble, like Sutton is now.

Via Albert Breer of SI: "Steelers coach Mike Tomlin asked if he reaches out to guys like Cam Sutton when they’re in trouble “I do but those conversations are between us.”
Has he talked to Sutton? “None of your business.”

Via Dave Birkett of the Detroit Free Press: "Steelers coach Mike Tomlin said he has reached out to ex-Lions and Steelers CB Cam Sutton in light of the off-field issues Sutton is dealing with. Asked if he talked with Sutton....Tomlin said, “None of your business.”

Tomlin did not say he successfully made contact with Sutton, just that he had reached out. It is truly no one else's business if he talked to Sutton, in the sense of telling reporters, or obviously what they talked about if so.

But if Tomlin talked to Sutton and also knows where he is, both of course unknown, Tomlin would surely be obligated to tell the appropriate authorities.
