Manager Paul Sturrock has a threadbare squad to select from for Saturday’s match against Exeter City.
Blues host the third placed Grecians at Roots Hall with seven players out or doubtful for their visit.
And that means Sturrock will wait until last minute fitness tests before deciding on his starting line-up.
“Mark Phillips (groin) isn’t’ training and Gavin Tomlin hasn’t trained either,” Sturrock told the official website.
“Gavin has been carrying a groin problem and it affected him in the last two games.
“Circumstances dictate at the moment that we will wait until the last moment to see how the lame and lazy are.”
Also joining the pair out of action is goalkeeper Paul Smith who suffered a neck injury and concussion in Tuesday’s 1-0 defeat at Gillingham.
The former Nottingham Forest stopper is due back in today after two days off and will be assessed my Southend’s medical staff.
“I went to the hospital after the game and he had a scan,” he said. “He has some bruising, a neck problem and concussion.
“He has been tucked up in his bed and is due in today to be assessed.
“Paul was asked at the hospital what team he played for and he didn’t know so it shows concussion can be very serious.
“He is fine now though and he seems very compos mentis so I am happy for him.”
Striker Elliot Benyon missed training on Thursday with a stomach bug whilst Luke Prosser (calf) and Ryan Leonard (hamstring) are rated as 50/50.
Striker Neil Harris (knee) is another player out but forward Barry Corr could make the subs bench against his former side after 17 months out injured.
And along with the injuries Sturrock is expecting a difficult match against an Exeter side back in League Two following relegation last season.
“Jamie Cureton is on fire as he is hitting things in from all over the pitch and they are finishing in the net,” he said.
“Their squad is very experienced if you look at the standard their players have played at.
“I am sure I will get a bit of stick from the Exeter fans as well due to my Plymouth connections but I have got that many teams I have managed with rivalries that is won’t be any different.”
