The experienced midfielder is desperate to kick-off his Premiership season but knows risking the injury could make it a lot worse in the long run.
So he will play no part against Southampton on Sunday but hopes to have a chance of facing Torquay in the Worthington Cup on Thursday.
Tim explained: “I picked up a knock in pre-season in Millwall, a bad ankle injury, but I’d got over that and was back to something like full fitness, been training for a couple of weeks, played a few reserves games but I unfortunately had a niggle in my thigh against Arsenal.
“Luckily it’s not a tear, just a few fibres and hopefully I’ll be back for the next game.
“It’s just the risk factor. I’m always happy to take that risk and play with knocks but unfortunately this sort of injury could get worse if I play on it, it could lead to a tear and then I’d be out for months.
“So for the sake of week or two it will be 100 per cent then I can look forward to starting my season.”
And his thoughts on the season so far? “We’ve had some tough games and hopefully we can build on what we’ve done,” he added. “But we need a win. We have a tough run coming up so the Southampton game is a massive game for us.”
Tim Sherwood has let his head rule his heart as he recovers from a thigh problem.
