Kamaru Usman admits UFC 310 may be too soon for him to compete.
Shavkat Rakhmonov (18-0 MMA, 6-0 UFC) was scheduled to challenge welterweight champion Belal Muhammad (24-3 MMA, 15-3 UFC) in the Dec. 7 main event at T-Mobile Arena in Las Vegas, but Muhammad was forced out due to a bone infection in his foot.
