Yeovil v Watford preview
Yeovil will assess two players ahead of their televised clash with Watford at Huish Park on New Year's Day.
Midfielder Ed Upson was forced to come off in the 5-1 away defeat at Huddersfield with an ankle injury before Czech goalkeeper Marek Stech followed him off the pitch after hurting his thigh and Johnson will wait for news on the pair.
If the duo fail to make it then Joe Ralls and Chris Dunn look likely to step in along with Everton loanee Shane Duffy who will be available to return to the Glovers defence having agreed a loan extension until the end of the season.
There is also a chance that Byron Webster could partner Duffy in the heart of the defence after he stepped up his recovery from a grade one hamstring tear.
Fernando Forestieri and Ikechi Anya, meanwhile, will be assessed as Watford make the trip to Yeovil on New Year's Day.
The pair missed Sunday's goalless draw at home to QPR with respective knee and groin injuries and will be monitored ahead of the Huish Park clash.
Wing-back Daniel Pudil will also be checked over once again having missed the club's last two matches with a hamstring problem.
But Almen Abdi (foot), Davide Faraoni, Essaid Belkalem and Tommie Hoban (all ankle) continue to remain on the sidelines.
