According to a report from Dave Meltzer on the latest Wrestling Observer Radio show, Braun Strowman is working hurt currently. Meltzer says it is likely a significant bicep or tricep injury.
However, Dave didn’t fault the injury for the removal of Braun Strowman (replaced by Sami Zayn) from the Money In The Bank Ladder Match. Instead, Dave is reporting that his removal from the match will be part of an overarching storyline that will play out in the next several weeks.
