#4. Brock Lesnar
Brock Lesnar is one Superstar on this list expected back sooner than most. Normally, Lesnar takes a hiatus between WrestleMania and SummerSlam time, but 2019 saw him return early to win the Money in the Bank briefcase, beat Seth Rollins for the Universal Championship, and then lose it back to him in the next PPV - SummerSlam.
While we're not sure whether Lesnar fits into the WWE Championship plans at SummerSlam, Tom Colohue revealed that WWE officials are 'desperate' to book a match between him and Bobby Lashley at The Biggest Party of the Summer.
It would be great to have him back sooner, but given the empty arena situation and the fact that WWE is reportedly only hoping for the return of crowds by the end of summer means that SummerSlam could be the earliest we see Brock Lesnar.
One can't deny the lack of star power on the WWE roster right now. Adding Lesnar to the mix would be big for programming, especially if he's in a non-title feud.
