Boxing champ Floyd Mayweather, Jr. has been hit with an $80,000 (£53,333) lawsuit over four tickets to a showpiece basketball match. The welterweight allegedly booked three courtside seats worth $25,000 (£16,666) each for the crunch tie between San Antonio Spurs and Miami Heat in June (13). He also allegedly bought a ticket for a place in the first row for $5,000 (£3,333) but the bill has not been paid, according to documents obtained by TMZ.com. Bosses of premium ticket agency White Glove International are reportedly now suing the star for the outstanding $80,000 bill plus interest. Miami Heat beat their rivals 95-88 to retain the National Basketball Association (NBA) title.
