You're thinking of Deion Sanders but... Unless I'm mistaken (which is always possible), this question has no answer.  Because the only man to play in both a Superbowl and World Series is Deion Sanders.  But Sanders did not play in both an NFL game and an MLB game on the same day.  He *tried* to, but his baseball manager refused to play him... On October 11 [1992], Sanders played for the Falcons at Miami, then took a charter flight to Pittsburgh for the Braves' playoff game that night, hoping to become the first athlete to play in two pro sports the same day. But Braves manager Bobby Cox didn't play him. Broadcaster Tim McCarver criticized Sanders and, three days later after Atlanta won the NLCS, Neon Deion's response was to dump ice water on McCarver. Nobody has actually PLAYED in both on the same day. On October 11, 1992 however Deion Sanders played for the Falcons against Miami in the NFL and was on the roster and in the dugout for the Braves in their NLCS game against Pittsburgh but he never actually entered the game. prime time? mm...thats a good question my guess is deion sanders.  I know he played for the Braves in '91 when they went to the world series and of course everyone knows he was one of the greatest cornerbacks of all time on the Dallas Cowboys when they had their Superbowl runs.
