The NFL approved a request by Jaguars receiver Mike Walker on Monday to officially change his last name to Sims-Walker, in honor of his late father. Walker announced plans earlier this month to change the name on the back of his jersey to honor Michael Sims, who died at 51 last December from colon cancer. The name change on the jersey will take effect this season. "That was a big loss," Walker said of his father. "You're thinking about the good times, the bad times." Source: The Florida Times-Union
