After a see-saw first two rounds, Chisora began hurting Pala on the inside. He rocked the 29 year-old into the corner.
Pala ended up with his back to ‘Del Boy’ and his arms down – apparently out of it.
Kristensen hastily called off the fight as Chisora kept throwing punches at a static Pala. Although the prone fighter walked away unhurt and may have been waiting for the official to call a break.
Either way, Chisora got the victory. The heavyweight improves his record to 19 wins and four losses. The triumph represents a 13th career stoppage and took place in front of a bemused crowd at the Copper Box Arena in London.
Prior to the debatable stoppage, Chisora, also 29, had been caught with two huge bombs by Pala. Chisora was wobbled in what was an untidy performance with a non-existent jab from the Finchley man.
Onwards and upwards for Derek Chisora.
Earlier in the night, Bradley Skeete defeated Colin Lynes at welterweight over ten rounds. Judges carded scores of 97-93, 96-93 and 96-94 to the 26-year-old.
Skeete picked up the vacant English title.
Also on the bill, Frank Buglioni continued his unbeaten run in the paid ranks with an eighth-round stoppage win over substitute Stepan Horvath.
The victory came via some wicked-looking body shots.
