Denver Broncos defensive end Antonio Smith plans to play in Super Bowl 50 on Sunday, even though he learned Wednesday of his father's death.
According to the Denver Post, Smith got a call from his mother telling him that his father, Marty Christopher Williams, had died in prison of complications from recent heart surgery.
Williams, 55, was convicted of first-degree murder in Oklahoma City in 1991 and was serving life in prison without parole in Lexington, Okla., according to the newspaper.
Smith, a 12-year veteran, joined the Broncos this season after being released by Oakland. He has had 21/2 sacks in the playoffs.
