NFL Star’s Brother-in-Law Prepares for Historic Transition with Rugby Training

San Francisco 49ers tight end George Kittle’s brother-in-law, former NFL quarterback and current professional baseball hopeful Trent Mullens—widely recognized in athletic circles through his family connections—has shaved his signature beard and officially shifted his athletic focus to baseball, stepping away from the gridiron’s rugby-style workouts to begin rigorous on-field baseball training.

The Transformation: A Clean-Shaven Start to Baseball Season

For months, training sessions caught on social media and shared by family members featured Mullens tossing rugby balls alongside George Kittle during off-season workouts. Those physical preparation videos highlighted a rugged, heavily bearded look that became synonymous with his multi-sport training regimen. Recently released training updates show a stark visual transformation. With his beard completely gone and a baseball glove firmly in hand, Mullens has transitioned entirely to baseball-specific drills, signaling a serious push toward professional diamond aspirations.

Family Ties and Athletic Background

Mullens shares a close training bond with George Kittle, the All-Pro NFL tight end for the San Francisco 49ers, through his marriage to Kittle’s sister, Emma Kittle. While Kittle dominates the line of scrimmage in the National Football League, Mullens has pursued a parallel athletic journey that bridges traditional football conditioning with baseball mechanics. The shift from throwing heavy rugby balls to tracking fastballs marks a distinct mechanical pivot, requiring rapid adjustments in footwork, rotational core strength, and throwing velocity.

What Comes Next for the Multi-Sport Athlete

With formal baseball workouts now underway, attention turns to how quickly Mullens can translate his raw throwing power and football-bred conditioning into viable metrics for professional scouts. Training updates from his camp indicate daily sessions focused on repetition and arm care. Observers and fans tracking his progress await further announcements regarding potential scout days, independent league opportunities, or formal workouts as he chases a professional baseball contract.
