(It’s embarrassing, okay? Let’s just say I’ll be on penicillin for a while, and leave it at that.) As first reported by MMAFighting yesterday evening, UFC heavyweight Alistair Overeem will be unable to fight former champion Junior Dos Santos at UFC 160: Velasquez vs. Bigfoot 2 (May 25th, Las Vegas), due to an undisclosed injury suffered in training. No word yet on the nature or severity of the injury, although it will reportedly require 4-5 weeks of recovery. As soon as news of the withdrawal broke, fellow UFC heavyweight Mark Hunt tried to organize a twitter assault to claim the replacement spot against Dos Santos. However, UFC president Dana White suggested that Overeem vs. Dos Santos will simply be postponed to sometime in the summer. Ah well. Would have been nice to see this happen again. The injury couldn’t come at a worse time for the hormonally fluctuating Overeem, who just followed up his nine-month licensing timeout with an upset knockout loss to Antonio Bigfoot Silva last month. If Overeem does meet Dos Santos this summer, the fight will come a full year-and-a-half since the Reem’s last victory over Brock Lesnar in December 2011 ”” not a good look for a guy who spent the previous four years unbeaten.
