Ross Fisher has established a three-shot lead after day two of the Portugal Masters.
The Englishman, who was suffering with an ankle problem after the first tee, added to his opening round of 66 with a four-under-par 67 to put him on 10-under overall.
Stephen Gallacher, who had joined Fisher at the top of the leaderboard overnight, hit a 70 to leave him three shots back with Austrian Bernd Wiesberger.
Padraig Harrington is joined by Sweden's Fredrik Andersson Hed on six-under, while Miguel Angel Jimenez ended the day on five-under with three others.
