The family of Navy running back Will McKamey remains by his side at a Baltimore hospital, hoping for signs of improvement after the sophomore underwent surgery over the weekend to remove a blood clot from his brain.

The freshman, who collapsed Saturday during spring practice, is at the University of Maryland Shock Trauma Unit, and his family has offered updates and requested prayers on social media. His mother, Kara Grubb McKamey, wrote Saturday on Facebook that “As of now Will is showing very little response. He is in a coma currently. In the past several hours since surgery we are seeing some very small improvements and reactions to light etc. We are hanging on to every small thing.”

His father, who was his coach at Grace Christian Academy in Tennessee, referred to a past concussion that required hospitalization in a tweet Sunday.

His mother elaborated on Will’s condition Sunday on Facebook, where she has a new profile picture: “#WILLMIRACLE Week of Prayer 3/23/14.”

Even though It’s been a really long day friends, we still feel your prayers! There is no new news, unfortunately we still have only small responses from Will. Randy and I appreciate each and every one of you! The photos of Will, the support, the prayers, the rally of all of you is unbelievable! It amazes me how this one kid is touching so many…from coast to coast! Our God is using Will for a huge platform right now! I know many of you wish you could be here with us but know that the Navy family has stepped in for our Knoxville family and they are providing an unbelievable support system! We miss you all however, but we feel your prayers across the miles! Pray for the Navy football players and coaches as well, they are all here and doing everything in their power to pull Will through! We love you all!

McKamey is a member of the Third Company at Navy.

On Monday morning, McKamey’s father continued to ask for prayers on Twitter.

Kara Grubb McKamey wrote on Facebook that her son’s collapse was “very similar to the last time,” when, as a high-school senior, he collapsed during a two-point conversion. He was hospitalized in Chattanooga for a few days, according to the Baltimore Sun, as doctors monitored swelling and bleeding in his brain. He did not undergo surgery and did not play high school football again.
