Ashley Cole is suspended as Chelsea take on Basle in Thursday night's Europa League semi-final second leg at Stamford Bridge, seeking to seal a place in the May 15 final in Amsterdam.
David Luiz, Ryan Bertrand, Ramires and John Obi Mikel are on yellow cards and may not be risked as the Blues take a 2-1 first-leg lead into the contest with the Swiss champions.
Ramires suffered a dead leg in last Sunday's defeat of Swansea and could be rested anyway, with Sunday's match at Manchester United in mind, while definite absentees are the ineligible Demba Ba and Oriol Romeu (knee).
Murat Yakin's is expected to name a largely unchanged Basle team from the one that lost last time out, with Kay Voser the only injury concern, while Gaston Sauro is expected to replace the suspended Aleksandar Dragovic.
A goalkeeper during his playing days, Larrieu joined Argyle in 2000 and made more than 300 appearances despite enduring a successful battle against testicular cancer.
