Pro Football Hall of Famer Deion Sanders said following his Jackson State coaching debut on Sunday that his personal items were stolen from the coaches’ office during the Tigers‘ 53-0 victory over NAIA Edward Waters, leading him to have “mixed emotions” about the day.

“For one, the kids played really well,” a visibly upset Sanders said during his postgame news conference, before continuing, “But while the game was going on, someone came in and stole every darn thing I have in the coaches’ office. Credit cards, wallet, watches. Thank God I had on my necklaces.”

The school later told ESPN that Sanders’ items were “misplaced and found.”

But Sanders disputed that the items were misplaced in a series of tweets later Sunday, saying that his assistant walked in on a man in the process of committing the theft.

Sanders went on to say that the items were retrieved since being reported missing.

Sanders, who also played Major League Baseball on top of being a two-time Super Bowl champion, is a first-time head football coach at the collegiate level. Previously, he was the offensive coordinator at Trinity Christian School in Cedar Hill, Texas, for three seasons.

Sanders announced on his podcast “21st and Prime” in September that he would be the next head coach at Jackson State. The Tigers’ game on Sunday was the first in a seven-game spring schedule that runs through April. It was also Jackson State’s first shutout since Sept. 6, 2014.

Jackson State next hosts Mississippi Valley State on Saturday, kicking off the Southwest Athletic Conference season.
