Somerset skipper Marcus Trescothick hailed Nick Compton as a world-class batsman after watching him hit a match-saving century at Durham.
The discarded England opener scored 100 not out at Chester-le-Street as the visitors batted through 73 overs on the final day to emerge with a draw - all done after treatment for a neck injury.
"It was a brilliant knock. Getting a hundred here at the Riverside is always tough, but he has been struggling with a neck injury for the last few days," said Trescothick.
"We have done everything we can. Our medical team has worked tirelessly to get him back in the position because we can see what he can do, we know what kind of players he is - a world-class player - when he gets into that environment.
"If we can just get him good enough and fit enough to get out on to the park, then we know can do well."
Compton and Craig Kieswetter (78) guided Somerset from a worrying 92-4 to 246-4 by the close having been set an unlikely 337 to win in 82 overs by Durham skipper Paul Collingwood.
"You can see what two international-class batsmen can do on a pitch where it's pretty flat, there's no turn and there's no swing," said Collingwood.
"You can see how they apply themselves and it was tough to get them out. We are putting teams under pressure for long periods, but we are just not quite finishing them off."
