Now a favourite fighting out of Dallas, Spence Jr escaped death in a serious car crash last year, but has chosen not to accept a soft touch on his return to boxing, with the WBC and IBF titles up for grabs.
The 31-year-old will look to prove he has shaken off any lingering effects from the accident, with a potential super fight with Manny Pacquiao or Terence Crawford up next, with the latter defeating Kell Brook last time out before agitating for his Top Rank exit to clinch the career-defining fights.
The 147-pound division is heating up with Garcia victorious last time out against Ivan Redkach and now looking to prove his worth at the elite level once again after falling short against Shawn Porter in 2018 for the WBC crown.
Porter would go on to defend the green and gold against Yordenis Ugas before relinquishing the belt to Spence Jr in September last year.
