Owen tweeted that half the squad have been hit by a rogue virus.
The striker revealed: "Not enjoying this. 3:40am and not getting an ounce of sleep. Bunged up, sore throat and cough. I hate being ill.
"I would like to blame 1 of my kids for my illness but I got it from the club. One of the lads brought it in. Half of the team have it now."
