Lions hopeful Mike Tindall could make his return in Bath's Zurich Premiership clash against Leeds on Saturday.
Tindall's last game for England was in November
The England centre, who leaves Bath to join Gloucester this summer, has been out of action since December with a damaged shoulder and foot.
"Mike will not start against Leeds but he could be involved on the bench," said Bath coach John Connolly.
"He is making excellent progress and we will make a decision on his selection on Friday morning."
The World Cup-winning star, 26, could be added to Sir Clive Woodward's 44-man Lions squad for New Zealand if he can prove his fitness.
"We would like him to play, because it could be his last game at The Rec in Bath colours and he has given us tremendous service," Connolly added.
A Bath win over Leeds should be enough to secure third place, and a title play-off encounter against Leicester or Wasps the following week
Meanwhile, Bath prop Matt Stevens is due to see a specialist in London after suffering a knee injury during the Premiership win over London Irish last Sunday.
Despite initial fears that Stevens, who will not face Leeds, could struggle to make the Lions tour, he is optimistic his injury is not as bad as first feared.
