Warriors-Wakefield is ON despite Covid scare
Chester revealed at his press conference on Thursday that another seven players have been forced to stand down and claimed the re-opening of schools may have been a contributory factor.
"There's been a couple of positive tests and another seven or eight players we've had to stand down on the top of that," he said.
"We need to have a look at what we're doing out on the field, whether we're doing everything possible to minimise the risk, and all the players need to look at what doing away from the club as well.
"We spoke today about potentially locking ourselves down for four or five days to get rid of the virus that is lingering around the players at this moment in time.
"It would give us chance to have a look at the training aspect and to give this place a real deep clean. If that's what it takes, then that's what we're going to have to do and fingers crossed that works for us."
Chester added: "This was always the worry as soon as schools go back, the risk becomes a lot higher and, without actually delving into it, that's obviously a reason we've had to stand some people down."
Chester says that, although he is down to just 17 players, Friday's Super League game against Wigan at Warrington will go ahead.
Chester says he was forced to bring in one player, second rower Matty Ashurst, from paternal leave simply to make up the team.
"These things keep happening and it's hard work at the minute," he added. "You prepare for a game on Friday and half your team gets pulled from underneath your feet in the last 24 hours.
"Last night I had 16 players and I had to make a phone call to Matty to ask him to join us for today for the team run. His wife had a baby on Monday but he came in today and he's fit and ready to go."
On top of the Covid withdrawals, Chester has lost winger Liam Kay and prop Eddie Battye to injuries sustained in last week's defeat at Huddersfield.
Kay, who rejoined the club from Toronto, will miss the rest of the season after being told he needs a shoulder re-construction, and Battye's loan spell from London Broncos has been put on hold due to a knee injury.
"It's unfortunate for Liam," Chester said. "He's just come back into the fold and he's in a tough spot at the minute. It's bad luck he didn't need at this moment in time. I feel for him but he's got three months now to get it right."
"We're all excited to see Tom back out there," Chester said. "The medical people have done a fantastic job, I just hope he gets a bit of luck now. He's a player who is very important to us and on his day he's one of best wingers in the competition."
Wakefield are the only club without a win since the resumption of the season six weeks ago and are reeling from a 29-6 defeat by the Giants.
"We had a good open and honest chat after the game," Chester said. "We had a video nasty and put it up in front of them. The senior guys took charge and led that meeting and came up with some real good targets for the next few games."
