Heavyweight James Thompson had to pull out of his Bellator 129 fight with Houston Alexander due to an injury, according to Bellator officials.

The heavyweight bout was scheduled to be one of the main card bouts for the Oct. 17 show at the Mid-America Center in Council Bluffs, Iowa. Bellator is now looking for a late replacement to stand in against the Nebraska native, Alexander.

The 35-year old Thompson was looking to extend his unbeaten streak to seven fights against Alexander, and is coming off a successful debut in Bellator with a win over Eric Prindle in June. Alexander, 42, has won three of his last four fights, including his last one at Bellator 117 against Matt Uhde.

Bellator 129 will feature a welterweight bout between MMA veterans Josh Neer and Paul Bradley in the main event.
