I initially thought that Benteke and Agbonlahor would cause Jones lots of problems with their pace and strength, but Jones handled them well even if he wasn't at his best. He won a number of aerial battles against Benteke, and he did a good job in suppressing Agbonlahor's influence. There were several instances where I was quite surprised at how he'd challenge Benteke when it wasn't really warranted, but for that aggressive approach, he did an okay job recovering his position.
Still, though, I agree with what ChrisG11 said. Jones did look as fresh as he was before as he was getting caught out more often, but given that, he still did a decent job at the back, and him being not as good as he was before didn't really hurt us as much.
