Coleman, who scored on touchdown runs of 14 and 3 yards in Sunday's 34-20 win over Tampa Bay, now has a baby boy and girl, who were born Saturday.
"This weekend has been amazing," Coleman said after the game. "The [birth] of my two children, my twins. It's just amazing to get two balls for them. It's just an amazing thing."
Coleman is the first of three team members expected to become a father to twins before next summer. Quarterback Matt Ryan recently announced that he and his wife, Sarah, will have twins in April. Assistant equipment manager Kenny Osuwah will become the father of twins in March.
"It's pretty cool," Ryan said. "Kenny and Tevin and myself, I don't know, man. They must be putting something in the Flowery Branch water at our practice facility."
Ryan said he thought Coleman played "awesome" on Sunday.
"I'm just so happy for him and his girlfriend to be able to have twins yesterday," the quarterback said. "Then he got some rest and came out to play the way he did today, scoring two touchdowns. He was able to take home two game balls for his boy and his girl. ... He's a professional, showing up and playing the way that he did. It's a pretty special weekend for him. We were all excited for Tevin."
Ryan was asked if he expects more of a challenge with twins.
"You know, I wouldn't know," he said with a laugh. "Without kids, I don't know what I'm getting into. But we're excited. I'm sure it will be a challenge, but also really special."
Kicker Matt Bryant, who has seven children, has two sets of twins, ages 6 and 16.
