Plymouth are boosted by the return of goalkeeper Luke McCormick from suspension ahead of their home clash with promotion rivals Watford.
McCormick was forced to sit out the 2-1 win at Bristol City following his controversial dismissal in the 1-0 defeat at Scunthorpe but is able to return in place of Rab Douglas, who has returned to Leicester after his seven-day emergency loan.
Central defender Krisztian Timar, who has just received his first international call-up for Hungary, is back in contention for Paul Sturrock's sixth-placed Pilgrims after completing a two-match suspension and could replace Marcel Seip.
Seip has partnered Scotland international Russell Anderson, whose loan spell from Sunderland has been extended until the end of the season.
Argyle's squad receives another fillip with the return from injury of Jim Paterson, who has recovered from the hamstring injury that has ruled him out for a month.
Watford manager Adrian Boothroyd will be without midfielder John Eustace for the trip.
Eustace begins a three-match ban after his sending-off against his former club Stoke last weekend so Lee Williamson or Al Bangura should return to partner John-Joe O'Toole at Home Park.
Eustace has also been charged by the Football Association with improper conduct after referee Rob Styles reported him for failing to leave the field of play in a timely manner, so he could get an additional two-game ban and a fine when the FA sit on Tuesday.
Jay DeMerit started in the unfamiliar role of right-back against the Potters as Leigh Bromby continues his fine form alongside Danny Shittu and that should continue, with the loss of Eustace seeing DeMerit reclaiming the captain's armband.
Former Wigan midfielder Damien Francis (knee) is still out while Gareth Williams is expected to miss the whole season after suffering a reoccurrence of a cruciate knee ligament injury.
The Hornets have drawn their last six games - failing to score in their last 259 minutes - but a win at Home Park could still take them back to the top of the Championship.
