Another death was reported Monday - this time a coach - at
Prestonwood Christian (Plano, Texas), where assistant Wade McLain collapsed during the squad's second football practice at approximately 6 p.m. He later
was pronounced dead.
Mr. McLain, 55, is survived by a wife and five children. He influenced countless others on the playing field and classroom. He also coached baseball and taught history at Prestonwood.
"We are deeply saddened to let you know that this afternoon, assistant varsity football coach Wade McLain died unexpectedly following the team's regular practice," the school announced on its website. "Please be in prayer for Coach McLain's wife, Becky, and their five children. We are deeply saddened by the loss of coach McLain yet are thankful in knowing he is in the presence of Jesus."
The cause of death is not known but is believed to be related to soaring heat in the Dallas region. Monday was the 31st straight day there that temperatures climbed to triple digits.
Here is a touching tribute to Mr. McLain in the
Dallas Morning News.
Mr. McLain's passing comes following the death of two players last week.
Lamar (S.C.) freshman Tyquan Brantley died on Saturday night after he collapsed during the morning session, the team's second day of official practice. Again, Brantley's cause of death is not known but temperatures soared to 101 on Saturday in Lamar.
"We are heartbroken at this terrible tragedy," Lamar school district superintendent Dr. Rainey Knight told South Carolina NBC affiliate WMBF.
