England batsman Kevin Pietersen will visit medical specialists this week to assess if he will be fit for the third Ashes Test against Australia starting at Edgbaston in Birmingham on July 30.
Coach Andy Flower told the England and Wales Cricket Board website on Tuesday (www.ecb.co.uk) that Pietersen had been struggling with an Achilles tendon injury which required four cortisone injections before the Lord's Test.
England won by 115 runs on Monday to go 1-0 ahead in the five-match series.
"He's going to be re-assessed later this week. He's got a couple of people he's going to be talking to and then the experts will make a decision on whether he's okay or not."
England will wait for medical bulletins on Pietersen, all-rounder Andrew Flintoff and pace bowler Graham Onions before naming their squad at the weekend.
Flintoff, who bowled England to victory at Lord's on Monday, had an injection on his right knee before the match. He said afterwards he was confident he would play a full part in the three remaining matches of his final Test series.
"We will listen to him and what he says about his body but we also take medical advice from the experts and we've got to take a very simple decision on whether he, like anyone else, is fit enough to contribute fully in a five-day Test match," Flower said.
Flower said Onions had sustained a blow on his shoulder while batting which affected his elbow when he bowled.
"He was a doubt to bowl on that last day, but I would imagine with the rest available between the second and third Test he would be fine," he said.
