As noted earlier on the site, former NXT Champion Sami Zayn made his main roster debut on last night’s RAW when he answered John Cena’s open challenge.
Zayn fell short in that match and then he was told by WWE doctors that he popped his shoulder out of place.
Dave Meltzer of the Wrestling Observer is reporting that the injury occurred during his entrance when he raised his arm.
WWE.com mentioned that Zayn will have an MRI later today to determine the extent of the injury.
