"I cry as I type this. Dev and I suffered the most painful experience of our lives," Michelle wrote on Instagram. "My pregnancy had resulted in a still birth at almost 8 months of being pregnant -- at exactly 31 weeks 2 days when we found out that the baby girl growing inside me no longer had a heart beat after being completely fine the week before at my last doctor's [appointment].

"We are so heartbroken. We are devastated. We are speechless. We are angry. We are sad. We are confused. We are numb."

Devin McCourty shared the post on Twitter. ESPN says McCourty had discussed his excitement for Mia's birth in recent interviews.

"While trying to cope with our family's loss, we appreciate the love and support we've already gotten, and just ask that you respect our privacy during this difficult time, since we have no answers to give anyway," Michelle wrote in her post.

Both Devin and his brother Jason are finalists for ESPN's Muhammad Ali Humanitarian Award. The honor goes to those "whose demonstrated leadership has created a positive impact on their community through sports."
