How to repair this load bearing block?

Damaged when builder knocked through inner leaf foundation blocks at door.

Cutting out and replacing would be structurally satisfactory. Is there any alternative?

If you want be a bit OCD you could use the tray as a shutter & feed some stiff concrete in there. 
Is it just that corner of the block that’s broken off?

Corner on that block, and corners or bigger chunks on other load bearing blocks

That was acceptable to architect. Not to SE.
Outcome: Patching the holes with 1:3 cement:sand mix (builder volunteered)
