Pompey are upbeat over the condition of Joe Devera.
However, fellow Northampton casualty Adam Webster faces a bleaker outlook.
The defensive duo were both forced out of the action during last night’s 2-1 Johnstone’s Paint Trophy defeat against the Cobblers.
Devera was substituted in the eighth minute of the Fratton Park fixture, while his replacement, Webster, left the field on the hour mark.
A lively Jed Wallace was also taken off at half-time – although that was not an injury issue.
Awford revealed Devera was suffering a stomach bug and is hopeful he will make Saturday’s visit of Mansfield.
Webster, however, left the ground on crutches with his right knee in a brace.
Pompey’s boss said: ‘Joe Devera was unwell before the game – he had slight stomach cramps, nothing too much.
‘He saw the doctor, spoke to the physio, spoke to me and it was a case of go on, have a go, see how you feel.
‘Within five to 10 minutes he knew.
‘I am hoping it’s a 48-hour bug and he is okay to get out there Saturday and we will keep on assessing him.
‘There is nothing significantly wrong with him, he just felt unwell.
‘Adam Webster just fell and his knee jarred. He has now got it in a brace.
‘They won’t know how bad he is until they get him back this morning and maybe Thursday.
‘Jed is fine, that was my choice to take him off.
‘He’s played a lot of games recently.‘
