England captain Michael Vaughan has been passed fit to play in the second Test against Pakistan, starting on Sunday.
Vaughan missed the first match, which England lost, after aggravating a knee injury.
"I have passed the fitness test and have had a good few last days," Vaughan told a news conference.
"It's always a slight risk when you come back from injury, but I am confident I can get through the game and that's really all that counts," he said.
"Day by day the recovery process has progressed well and it is getting better," he added.
The England captain said with his return it was obvious that either Paul Collingwood or Ian Bell would miss out.
England are keen to have their captain back and raise their intensity level after being outclassed on the final day of the first Test in Multan after controlling the first four days.
England lost by 22 runs on an exciting final day after needing 198 runs for a win.
Vaughan has led England to 19 wins in 31 Tests since taking over from Nasser Hussain two years ago, including the recent 2-1 Ashes win.
"It's tough because in the circumstances we have to win both Tests to win the series. Winning the toss and getting off to a good start will be crucial tomorrow. We want to put Pakistan on the back foot as early as we can."
He said the toss would be vital as the wicket was very dry in this part of the world. "Whatever we do tomorrow we have to make sure we start well and put Pakistan under pressure as we did in Multan.
"We were going at a position when we could have won that game. We performed well for four days in Multan and on last morning we got unstuck. We just have to try to improve in this match."
Asked about the threat posed by Pakistan leg spinner Danish Kaneria to his batsmen, Vaughan said he was probably the best young leg spinner in the world.
Kaneria took four wickets on the final day in Multan.
"He is a good bowler and we knew he would cause some concern for us on the final day. He has a few different deliveries," he stated.
