Instead of checking on A.J. Brown, first-year Titans offensive coordinator Arthur Smith screamed at the rookie wide receiver for falling during practice. Now the coach is showing remorse.

Smith apologized to the second-round pick multiple times for yelling “Stop f–king falling down and finish!” at Brown on the first day of training camp, according to ESPN. It turned out Brown had a hamstring injury, and Smith “felt like a jerk” for yelling at the second-round pick.

“If I had known he was hurt, I would not have gone over to do that,” Smith told reporters. “As soon as I realized it, I felt awful, so I walked over and said something and then I walked to the training room and apologized to him and I told him that. My wife gave me an earful about it, too. There was a video going around.”

Smith, 37, is in his ninth season with the Titans. He was their tight ends coach the previous three seasons and took over the coordinator job after Matt LaFleur became the Packers’ head coach.

Brown, a 22-year-old out of Ole Miss, accepted his coach’s apology.

“He apologized a couple of times. He felt bad for that one,” Brown said. “He’s a great guy and he was just apologizing, saying he said he didn’t know what happened.”
