Midfielder Returns To Memorial Stadium
The 29-year-old, who started his career at the Memorial Stadium, has found first team appearances hard to come by in recent months.
With Michael O’Connor and Michael Brown’s midfield partnership flourishing, Lines has had to make do with a place on the bench more often than not.
In his previous spell with the Pirates, he made over 150 league appearances and scored more than 20 goals.
Should Darrell Clarke’s side finish in the Conference Premier play-off places, Lines will remain at the club until their involvement concludes.
Speaking of Lines’ loan move, Vale boss Rob Page said: “I’ve said all along that I won’t stand in anyone’s way who has a chance to go and play games.
“Chris has been unfortunate in that he got suspended against MK Dons and, due to the form of Michael Brown and Michael O’Connor, has found it difficult to win his place back.
“We’re sure he will be a great asset to Bristol Rovers and will enjoy his time there.”
