According to the Wrestling Observer, the current plan as of Thursday was for Daniel Bryan and Randy Orton to begin their match for the vacant WWE Championship at 10:25PM ET on Sunday night. That would give the two 35 minutes to work in the main event of WWE Battleground, including any extra interference or segments they have planned.
One idea that has been going around is solidifying Big Show's role as either a babyface or a heel, and having him either help Daniel Bryan win the WWE title, or turn on him and cause Randy Orton to win. Historically, this would not be the first time Big Show served as an enforcer for the McMahon family, as he made his WWE debut as the muscle for the original WWF Corporation.
