Haskell and Marler were unavailable for England's victories over Italy and Wales due to suspension.

They were included in Jones's pre-tournament squad and return to the fold as the competition takes a break ahead of round three later this month.

England will train against Georgia on Tuesday and Wednesday as part of their build up to the Calcutta Cup clash with Scotland on 24 February.

Haskell and Marler will be eligible to play at Murrayfield and will hope to force their way back in despite impressive performances from England so far.

Nathan Hughes and Denny Solomona are also in the extended squad, but Alex Hepburn, George Kruis and Sam Simmonds do not feature despite being in the 23 that beat Wales – the latter starting at number eight.
