Siyar Bahadurzada said he wanted to get back into action as soon as possible after he found out his hand wasn't broken. He'll get his wish as a late replacement for an injured Yoshihiro Akiyama. UFC.com has the news:
After a spectacular UFC debut in April that netted him a 42 second knockout of Paulo Thiago, Siyar Bahadurzada will jump right back into action at UFC 149 in Calgary when he replaces the injured Yoshihiro Akiyama against longtime welterweight contender Thiago Alves. The bout will take place at Scotiabank Saddledome on July 21st.
There's no word as to what is actually wrong with Akiyama. As mentioned above, Siyar is coming off his excellent UFC debut at UFC on Fuel 2 last month. Alves is coming off a late submission loss to Martin Kampmann at UFC on FX 2 in March. The bout is expected to stay on the main card of the Calgary event, which is headlined by a UFC featherweight title bout between champion Jose Aldo and challenger Erik Koch.
