White scored the winning touchdown in overtime as the Patriots beat the Atlanta Falcons 34-28. What happened to the ball after that is anyone's guess, White said on ESPN's "Mike & Mike" show on Monday.
"I have no idea what happened to the ball," White said. "I have no idea. I dropped it at some point when I was running around, I don't know."
White, in a separate interview on The Dan Patrick Show on Tuesday, said he is hopeful that an equipment manager grabbed the ball and that it is in the possession of the Patriots.
"I wasn't thinking in that moment. I was too busy sprinting down the field," he said.
White said he did keep the football from the first touchdown he scored in the historic comeback. White had 14 receptions for 110 yards and one touchdown and added two rushing touchdowns in the victory.
After the game, his teammates, including MVP Tom Brady, were quick to say he deserved a share of the MVP honor. In years past, the Super Bowl MVP award came with a car. After the Patriots beat the Seattle Seahawks in Super Bowl XLIX, Brady was awarded MVP and gave the truck to Malcolm Butler, who made the game-saving interception in the final seconds.
Brady said he would do the same this year with White -- but there is no truck to give. According to an NFL spokesman, a vehicle hasn't been part of the MVP award for the past two Super Bowls.
White was asked about Brady's promise of the truck and said, "I haven't actually received it yet. I don't know how that works."
White said, "it's pretty cool that he's humble enough to give me the car," adding that Brady is a "great teammate."
It is unknown if Brady still plans to give White a vehicle of some kind.
